Crynodeb
Mae’r arolwg archaeolegol o uwchdiroedd Arennig <strong>Fawr</strong>, a gynhaliwyd yn 2010, yn
ymdrin ag oddeutu 32 cilometr sgwâr o’r ardal fynyddig i’r gorllewin o’r Bala a Llyn
Celyn, ac mae’n cynnwys darn o dir comin ar wahân ar ochr ogleddol tref y Bala.
Llethrau creigiog serth a rhostir agored yw prif nodweddion y tirlun hwn, sy’n gorwedd
bron yn gyfan gwbl rhwng cyfuchlinau 230m ac 850m. Cafodd yr arolwg ei gynnal drwy
gerdded trawsluniau rheolaidd o 30m, a’r nod oedd dod o hyd i safleoedd
archaeolegol o bob cyfnod. Cafodd cyfanswm o 935 o safleoedd ei gofnodi. Roedd 9
o’r rhain wedi’u cofnodi o’r blaen yn y Cofnod Henebion Cenedlaethol.
Cyfran fach o’r archaeoleg yw’r safleoedd cynhanesyddol, sef carneddau copa o’r Oes
Efydd a gweddillion tameidiog maes carnedd bach a allai ddyddio o’r cyfnod
cynhanesyddol. Cafwyd ychydig o dystiolaeth o ffordd Rufeinig a arferai gysylltu’r
caerau atodol yng Nghaer Gai a Thomen-y-mur.
I ddiwedd y cyfnod canoloesol ac wedyn y mae’r mwyafrif o’r safleoedd yn perthyn. Er
bod rhywfaint o dystiolaeth ddogfennol bod gwartheg wedi’u magu ar borfeydd yr
uwchdiroedd, mae’r dystiolaeth ffisegol o’r cyfnod canoloesol wedi’i chyfyngu i
lwyfannau adeiladau a sodlau cytiau hir. Roedd y rhain i’w gweld yn arbennig ar ochrau
dwyreiniol cysgodol Arennig <strong>Fawr</strong> a Moel Llyfnant ac roedden nhw’n aneddiadau
tymhorol o fath a oedd yn dal i gael eu defnyddio tan y ddeunawfed ganrif.
Parhawyd i bori gwartheg ar ffermydd parhaol yn yr uwchdiroedd tan y bedwaredd
ganrif ar bymtheg ar ochr orllewinol esgair Arennig <strong>Fawr</strong>. Nodweddion arferol y
porfeydd caeedig hyn yw waliau cysgodfeydd, a defnyddio’r beudy bach yn y caeau i
gadw’r da byw dros y gaeaf. I’r ddeunawfed ganrif ac wedyn y mae’r mwyafrif o’r
safleoedd amaethyddol yn ardal yr arolwg yn perthyn, sef corlannau defaid a
chysgodfeydd cyntefig i fugeiliaid yn bennaf. Ceir torlannau mawn yn helaeth ac mae’r
rhain i’w gweld ar 250m ac mor uchel â 700m. Câi mawnogydd tir uchel eu defnyddio’n
eang ym Meirionnydd a daethpwyd o hyd i lawer o dorlannau bach, afreolaidd yn aml.
Cafwyd tystiolaeth o fwyngloddio manganîs tua diwedd y bedwaredd ganrif ar
bymtheg mewn pedwar lle - Mynydd Nodol, Moel-y-garth, Pistyll Gwyn a Moel
Llyfnant. Ym Mynydd Nodol y cafwyd y gweithfeydd helaethaf ond yr un yw safleoedd
mwyngloddio yn y bôn ble bynnag y maen nhw - ffosydd archwilio, gweithfeydd
ehangach ar y brig, lefelau wedi’u hagor yn ochr y bryniau a siafftiau. Mae’r safleoedd
prosesu wedi’u cyfyngu i loriau naddu a biniau mwyn. Nifer fach yn unig o safleoedd
chwarela a welwyd, bron bob un yn perthyn i ddechrau’r ugeinfed ganrif, gan gynnwys
chwarel lechi fach a chwareli gwenithfaen.
Mae’r adroddiad yn gorffen gydag argymhellion ar gyfer gwaith cofnodi ac ymchwil at
y dyfodol.

Summary
The <strong>Arenig</strong> <strong>Fawr</strong> uplands archaeological survey, undertaken in 2010, covers
approximately 32 square kilometres of the mountainous region to the west of Bala and
Llyn Celyn, and includes a detached area of common land on the north side of Bala
town. The landscape is characterised by steep craggy slopes and open moorland and
lies almost entirely between the 230m and 850m contours. The survey was conducted
by walking regular 30m transects and aimed to identify archaeological sites of all
periods. A total of 935 sites were recorded, of which 9 had been recorded previously in
the National Monuments Record.
Prehistoric sites are a minor component of the archaeology, comprising Bronze Age
summit cairns and fragmentaryu remains of a small lcairnfield that may be of
prehistoric date. Slight evidence of a Roman road was found that linked the auxiliary
forts of Caer-Gai and Tomen-y-mur.
The majority of sites belong to the late medieval and post-medieval periods. Although
there is some documentary evidence of cattle rearing on the upland pastures, physical
evidence of the medieval period is confined to building platforms and the footings of
long huts. These were found especially on the sheltered east sides of <strong>Arenig</strong> <strong>Fawr</strong> and
Moel Llyfnant and were seasonal dwellings of a type that continued in use to the
eighteenth century.
Pasturing of cattle continued in permanent upland farmsteads into the nineteenth
century on the west side of the <strong>Arenig</strong> <strong>Fawr</strong> ridge. Characteristic features of this
enclosed pasture are shelter walls, and the use of the small field cow house, or beudy,
for housing livestock over winter. The majority of agricultural sites throughout the
survey area belong to the eighteenth century and later and are mainly sheepfolds and
primitive shepherds’ shelters. Peat cuttings are widespread and are found at 250m and
as high as 700m. Exploitation of peat from high ground was widespread in <strong>Merioneth</strong>
and many small, often irregular cuttings were identified.
Evidence of late-nineteenth century manganese mining was found in four separate
areas – Mynydd Nodol, Moel-y-Garth, Pistyll Gwyn and Moel Llyfnant. The most
extensive workings are on Mynydd Nodol but in essence mining sites are of the same
types wherever they are found – prospecting trenches, larger opencast workings, levels
driven into the hillside and shafts. Processing sites are confined to dressings floors and
ore bins. Only a small number of quarrying sites was identified, almost all belonging to
the early twentieth century, and includes a small slate quarry and granite quarries.
The report concludes with recommendations for future recording and research.

1.0 Introduction
The <strong>Arenig</strong> <strong>Fawr</strong> uplands archaeology survey area centres on one of the highest peaks
of southern Snowdonia, to the west of Llyn Tegid and south-west of Llyn Celyn, in the
communities of Llanycil and Llanuwchllyn (fig 1). The combined survey area was
approximately 32.5 square kilometres.
The landscape is dramatic, characterised by a large natural lake and its craggy
precipitous slopes, the steepest of which were excluded from the survey area. It is
principally a moorland landscape of heather, bracken and grass on the slopes of <strong>Arenig</strong>
<strong>Fawr</strong>, Mynydd Nodol and Moel Llyfnant, the summits of which are 854m AOD, 539m
AOD and 751m AOD respectively. Llyn <strong>Arenig</strong> <strong>Fawr</strong> is a natural lake on the sheltered
east side of the <strong>Arenig</strong> <strong>Fawr</strong> ridge. The geology of <strong>Arenig</strong> <strong>Fawr</strong>, which is directly
relevant to extractive industries, comprises volcanic rocks, mainly in the form of ashes
and agglomerates derived from lava flows, overlain in places by Ordovician shales.
Igneous intrusions, in the form of granite, are found on the north side of <strong>Arenig</strong> <strong>Fawr</strong>.
A large proportion of the survey area is common land belonging to the Crown Estates,
but has been fenced into large sheepwalks by the commoners. Those areas in private
ownership are of similar moorland character but, except for the steep ground on the
west flank of <strong>Arenig</strong> <strong>Fawr</strong> and the moorland north-west of Moel Llyfnant, are enclosed
with drystone walls. A detached area of common land on the north-west side of Bala,
known as Gwastadros, has the same moorland vegetation, with frequent boggy areas,
but is lower, rising only to 360m AOD, and is not enclosed.
With the exception of Gwastadros, the survey area is a Site of Special Scientific
Interest, and falls within the Migneint-<strong>Arenig</strong>-Dduallt Special Protection Area for its
ornithological interest, and is a Special Area of Conservation on account of its
important habitat types (blanket bog, dry heath, peat-stained lakes and pools). The
whole of the survey area is within Snowdonia National Park and the majority is
designated as Access Land.
The field survey was undertaken between May and October 2010 by Richard Hayman
and Wendy Horton, with grant in aid from RCAHM Wales under the Uplands
Archaeology Initiative.
2.0 Methodology
The project aimed to identify and record the resource through rapid, systematic field
survey. Archaeological remains of all periods were considered equally. RCAHM Wales
undertook aerial photograph mapping of the area, which was consulted through the
fieldwork phase. The regional Historic Environment Record was consulted prior to the
fieldwork, which yielded records of 26 archaeological sites) and RCAHM Wales
provided digital copies of the county series Ordnance Survey maps at 6-inch and 25-
inch scales. Tithe surveys were also consulted, but a search did not discover any useful
estate maps covering the area that have not previously been discussed.
The area was divided into transects 30m apart, except in areas where archaeological
sites were sparse. These were divided into 50m transects. The location (NGR) of each
1

site was established by a hand-held Global Positioning System receiver (GPS). Written
descriptions, including approximate dimensions, were made in the field and
photographs were taken of all important sites and when conditions were favourable.
3.0 Results of survey
The survey identified 935 sites, giving a site density of 28.8 sites per square kilometre.
The distribution of sites is influenced by altitude, topography, geology and vegetation
cover.

Table 1: sites grouped by contour.
Altitude is factor in the location of some sites, and the variation in altitude of over
600m calls for some comparison (table 1). Gwastadros lies between the 220m and
360m contours. It is also close to permanent farmsteads that encircle the common. It
archaeology comprises mainly peat mounds on the level areas, but also tree mounds
and enclosures of the nineteenth century, as if an attempt was made to create wood
pasture, and a pillow mound (nprn 511387). The other area where the ground is level
and the altitude is below 350m is near Hafod y Garreg, and here also a large number of
peat stacks were discovered. The high ground of the <strong>Arenig</strong> <strong>Fawr</strong> ridge includes
evidence of peat cutting over 700m AOD but no peat stacks, as well as simple sites
such as marker cairns and primitive shelters. It is peat cutting that accounts for the
relatively high density of sites above 650m and below 350m. Settlement and
agricultural sites are found between the two extremes, concentrated between the
350m and 450m contours and in sheltered positions.
Tables 2 and 3 group the sites according to period and Broad Class. The paucity of
prehistoric sites may be accounted for by the formation of peat in later prehistory and
by the dense heather vegetation on high ground, both of which will have served to
make prehistoric features difficult to recognise. The overwhelming majority of sites
belong to the post-medieval period, although it is rarely possible to distinguish
2

etween medieval and post-medieval settlement sites. Post-medieval sites are
dominated numerically by the archaeology of sheep farming, peat cutting and
manganese mining.

3.1 Prehistoric sites
There were very few prehistoric sites. A large cairn on the summit of <strong>Arenig</strong> <strong>Fawr</strong> has
been considerably mutilated, and the cairn material has spread beyond its original
circumference (nprn 43852) (fig 3). It was built on the highest point of the ridge of hills,
and has a near panoramic view of surrounding lowlands, blocked only on the southwest
side. Summit cairns are common in <strong>Merioneth</strong>shire and it has been suggested that
they were reserved for high-status burials, on sites chosen because they are
conspicuous from a distance (Smith 2003, 115-16). The cairn has a drystone shelter
built on to its summit, as well as a memorial to an air crew that crashed on the
mountain in 1944, and a modern concrete triangulation pillar. Its names, Eglwys
Glominog and Moel yr Eglwys, are not readily explicable. A tradition that a hermit’s cell
was built on the summit of <strong>Arenig</strong> <strong>Fawr</strong> was current in the early modern period, and
was well known enough for an engraving of it to appear in a posthumous edition of
William Stukeley’s Itinerarium Curiosum (1776), although it is almost certain that
Stukeley never visited the site (RCAHMW 1921, 147). Such stories may have derived
from the presence of stone shelters on the summit, one of which may have been
misinterpreted as the ruins of a chapel. The ‘chapel’ has remained part of the local
folklore.
There is a cairn at Cefn Coch (nprn 303153), a summit cairn on a low ridge below Moel
Ymenyn, which is also much mutilated and diminished. It is 700m north of a track which
crosses the central highlands of <strong>Merioneth</strong>, giving access to the coast (nprn 511404).
The track has been interpreted as prehistoric on the basis that there are standing
stones further west along the route, and consequently that the track was a determining
factor in the site of the cairn (Bowen and Gresham 1967, 83, 60). The summit of Moel
Ymenyn does not, however, have a Bronze Age cairn of its own.
A cairn on Moel y Garnedd, Gwastadros, was identified in the early twentieth century
as constituting only a few remains (RCAHMW 1921, 145). There is no longer any visible
structure on the surface, and therefore the cairn is a doubtful one, its existence
perhaps suggested by the place name. However, following a survey of prehistoric
funerary and ritual sites in <strong>Merioneth</strong> the site is still considered to be a cairn in the
Historic Environment Records (HER) for Gwynedd. A field visit in 2000 identified an arc
of turf-covered stone that might constitute the kerb, which would give a diameter of
approximately 11m, but the present authors thought that it was a natural occurrence.
The site is also now occupied by a modern triangulation pillar, constructed of stone
quarried from nearby (and clearly not stone robbed from a cairn as has previously been
suggested). It is on the summit of the hill, which is the highest point of Gwastadros, and
offers panoramic views, and a vista to Llyn Tegid.
Other possible cairns, or barrows, have been rejected, such as a mound on Pistyll Gwyn
that appears to a natural conical mound (nprn 511413). A stone circle recorded in the
HER on the lower, north-east slopes of Moel Llyfnant, was not found. Hitherto
unrecorded cairns were found half-buried in peat, but with no evidence to suggest that
they are prehistoric (nprn 510727, 510835). They may be clearance cairns, which are
found occasionally on the upland, including a small cairnfield of twelve cairns above
Amnodd Wen (nprn 511405) (fig 4). The small cairns were found on sloping ground
bordered by level ground to the west and east and may have been part of a larger
cairnfield that has been obscured by peat
8

3.2 Roman sites
A section of probable Roman road was identified (nprn 511140), part of the 19-
kilometre route that connected the auxiliary forts at Caer Gai, near Llyn Tegid, and
Tomen-y-mur, north of Trawsfynydd (fig 5). However, evidence of this road is difficult
to identify on the ground. The line of the road, as proposed by Irvine, more or less
follows the line of a relict bank (nprn 511169) as it travels north-west across the lower
slopes of Moel Llyfnant (Irvine 1956, 62). During fieldwork a short section of a track
was identified on this line on the upper slopes of Ffridd Castell and Ffridd Uchaf, where
it forms a ledge in the hillside. The road is said to be more visible on the higher ground
to the north-west, on Moel y slates, where it is paved (Bowen and Gresham 1967, 256).
Lower down, and beyond the present survey area, a section of track was discovered in
1953 and comprised a packing of pebbles 0.25m deep, with a kerb and ditch, but its
location is almost exactly on the site of the probable prehistoric trackway described
above (nprn 511404). In the Lliw valley the course of the road proposed by Irvine was
local knowledge in the nineteenth century, and its existence is well known to the
present owner, who lives lower down the valley at Buarth-meini.
3.3 Medieval and post-medieval settlement and agriculture
Settlement
There were many sites associated with the late-medieval and post-medieval period.
Documentary evidence provides some information of medieval settlement, and of the
relationship between the upland areas within the survey area and the neighbouring
lowland. Llanycil and Llanuwchllyn were within the commote of Penllyn. Llanycil
included several townships, or trefi, some of which can be identified on modern
Ordnance Survey maps on the enclosed ground just beyond the limit of the present
survey area, and includes Streflyn and Maestron, together with two others that are now
farms (Cyffdy, Gwernhefin) (fig 2).
The townships were the foci of medieval settlement, beyond which was the friddoedd,
a band of unenclosed ground on the margins of settled agriculture, where there was
advance in the late medieval period by the creation of new dispersed farmsteads, and
where summer dwellings were established. Temporary dwellings were well established
in the late sixteenth century in <strong>Merioneth</strong>, as shown by a case heard in the Court of
Exchequer in which defendants were accused of taking stone and timber from ruined
summer dwellings (Thomas 2001, 211-12). Much of this mountain pasture was
subsequently enclosed, and some of it came within the bounds of the present survey.
Fridd place names are found on the modern Ordnance Survey, but the Tithe survey of
1838 quotes many other examples of Fridd names. They refer to land that was taken
from the common and is now enclosed and in private ownership, even though they
provide only rough mountain pasture. The place names are probably therefore of
comparatively recent derivation. Encroachment on the common had taken place by the
eighteenth century, and can be seen where field walls have been constructed. The
practice of building field walls, even at high altitude and on precipitous terrain, was
noted in the late eighteenth and early nineteenth centuries (e.g. Evans 1812, 892)
That some of the summer dwellings later became permanent farmsteads, and the land
around it enclosed, is suggested by some place names, such as the farmsteads Hafod-ygarreg
and Hafotty filltir-gerig (fig 2). Both lie beyond the present limit of mountain
pasture and were not part of the uplands survey. This provides further evidence that
9

the area of common mountain pasture has shrunk over the past few centuries. It has
been noted elsewhere that in <strong>Merioneth</strong> hendre and hafod are often found so close
together that it hardly seems to have been worth moving from one to the other (Davies
1973, 21). Hafotty filltir-gerig is a prime example, only 1 kilometre west of the hendre
(nprn 510955). Another example might be Fotty (nprn 511171), which is less than 700m
north of Hendre Blaen Lliw (nprn 28488), and 500m north east of Blaen Lliw Uchaf
(nprn 28173).
One of the royal hafodydd of Penllyn was Amnoth, where permanent farmsteads at
Amnodd Wen and Amnodd Bwll remained inhabited into the twentieth century. In
1547 Rhydderch ap Dafydd ap Rhys and Cadwaladr ap Robert were demised the
pasture rights of the ffriddoedd of western Penllyn, including Amnodd, which were
described as open barren pasture and mountain, except that by the 1540s Amnodd
already included 20 acres of newly enclosed meadow (Longley 2006, 79). This may
refer to ground below the present farmsteads which is now forestry and was not
included in the survey. At Boch y Rhaeadr, which is just north of the survey area and on
the western edge of Llyn Celyn, was a grange belonging to Basingwerk Abbey (fig 2).
However, there is no physical evidence of upland cattle pasture (vaccary) of medieval
date. The adjoining upland pasture of Moel y Garth is steep, although a platform (nprn
511183) and at least one hut (nprn 511338) may be medieval.
On the south-west side of the survey area, above Blaen Lliw, is a massive boundary bank
(nprn 511159) of probable medieval date. Other than this, the earliest evidence of
dwellings and subsistence on the upland pastures is of building platforms, long huts
and (possibly) sheepfolds. Only two building platforms were identified without the
outline of a hut. One is on the sheltered north side of Mynydd Nodol (nprn 511183),
where it is surrounded by later mining remains (fig 6); another is on Moel y Garth, on
the sheltered east side of <strong>Arenig</strong> <strong>Fawr</strong>, where there are huts and folds in close
proximity. Neither conformed to the type of enhanced platform noted elsewhere in
<strong>Merioneth</strong>, whereby the hood was raised to improve drainage, of which 147 examples
had been recorded by 2006 (Longley 2006, 62). They are large platforms, 17m by 7m
on Mynydd Nodol, much larger than the average for <strong>Merioneth</strong> of 8-10m by 4-5m
(Longley 2006, 63).

Figure 7: long hut above Filltir-gerig (nprn 510965).
Figure 8: Long hut on west side of <strong>Arenig</strong> <strong>Fawr</strong> (nprn 511080).
Most of the medieval and post-medieval settlement evidence was in the form of long
huts. Long huts occupy natural ledges in the hillsides, or else artificial platforms. One
such hut (nprn 510965) on a levelled platform on the steep slope of Clogwyn Maen
Grugog, measures 9.5m by 5m (fig 7). The hood appears to have been retained by a
curved wall, which survives only at ground level, but conforms to the enhancement of
platform sites noted above. Some huts have rounded end walls, for example below
Moel Llyfnant, where the hut (nprn 511115) is 8m by 4m. These are assumed to be the
earliest type. One hut (nprn 511244) on Moel y Garth had only one rounded end wall.
Some huts were found at high altitude, of which the highest was at 642m AOD (nprn
511079). Fireplaces were positively identified in three huts, and are therefore
considered to be the latest type of simple hut. One (nprn 511080) was found on the
steep ground on the west side of the <strong>Arenig</strong> <strong>Fawr</strong> ridge at 612m AOD, with a small fold
and a shelter wall close by (fig 8). The pitch of the roof was clearly visible in the gable
and the side walls stand to their full height of 1.6m. The gable end was also clearly
visible in another small hut (nprn 511226), on Moel y Garth. Both of these huts are
comparatively small, 4.5m by 3.1m (giving internal dimensions of 2.5m by 1.8m) on
11

<strong>Arenig</strong> <strong>Fawr</strong> and 5.7m by 4.4m (giving internal dimensions f 4.4m by 3.2m) on Moel y
Garth. The other hut containing a fireplace is on Moel Ymenyn and is even smaller, with
internal dimensions of 3m by 1m (nprn 511398). In all three cases the walls appear to
have been dry-built. These huts cannot have been built before the seventeenth
century, and are probably much later. Although there is documentary evidence that the
practice of seasonal occupation of the mountains had ceased by the end of the
eighteenth century, they may have been built and occupied by shepherds.
Sheep farming
The tradition of moving up on to summer pastures appears to have died out by the end
of the eighteenth century. Although the practice was described in 1812 in upland
Caernarfon by John Evans, other evidence suggests that his was a romanticised account
(Evans 1812, 319). George Kay, in his survey of farming practices for the improving
Board of Agriculture, had already written that
I had been informed, that it was a common practice in the county, for families to
go up to the mountains, in the summer season, to attend their flocks, and to
reside in huts, in which they made cheese; but, upon minute enquiry, I found that
no such custom existed. On the contrary, the wedders only are sent up, and the
ewes are always kept on low grounds, with their lambs’ (Kay 1794,
Caernarvonshire, 17).
This accords with the practice of sheep farming in the <strong>Merioneth</strong> uplands, where ewes
were brought down at the lambing season, and lambs were kept on lower ground for
their first winter. The same survey makes no mention of black cattle pastured on the
uplands (Kay 1794, <strong>Merioneth</strong>, 14), although it was also said that goats also browsed
among the sheepwalks (Evans 1812, 891).
Some of earlier huts may later have been used as sheepfolds. One example was found
on Banc Calch (nprn 510919) where the original hut measured 9m by 8m and includes a
possible fireplace, to which an L-shaped cell was wrapped around the structure by
means of a later drystone wall, almost certainly for a fold. Also, some of the sites
interpreted as sheepfolds may have really have been huts. The proximity of folds to
earlier settlement is well known, and examples of it were found during the survey. For
example, a large sheepfold (nprn 510721) is on steep ground below Carreg Lefain,
close to which are three long huts (nprn 510722, 510723, 510724), one of which is
marked as a sheepfold on Ordnance Survey maps. There are several sheepfolds
alongside the upper reaches of Afon Llafar, and in one instance there are two multicell,
multi-period sheepfolds (nprn 510924, 510925) close to four possible long huts
(nprn 510922, 510923, 510926 and 510927). In each case it appears that the hut has
been robbed of stone to build the fold.
Sheepfolds, and occasionally sheep washes, are found throughout the survey area,
except for the very flat or very steep ground. These folds vary in their scale and
complexity, and in their date. Many folds are identified on the county Ordnance Survey
maps but on inspection proved to be either huts or structures associated with mining.
The folds conform to the farming practices suggested by the documentary evidence –
that they were used for sorting sheep rather than milking them.
Most of the simple sheepfolds are rectangular, for example at Hafod y Garreg (nprn
510777, 510759). Many are similar in size to huts and it can be difficult to distinguish
12

etween them, especially as so few huts have fireplaces. Structures on sloping ground
have been interpreted as small folds, as have structures which are not quite
rectangular, for example a small fold on the banks of Afon Llafar (nprn 510914), where
the fold is approximately 9m by 6m but the walls curve inwards at one end and there is
an associated guide wall. Another structure nearby (nprn 510913) measures 8m by 4m,
and has attached to it another unit of similar dimensions which is defined only by
boulder footings. A definitive interpretation is not appropriate in this case: it could
have been a two-cell fold, where part went out of use, or a hut with a garden wall.
The round folds are probably the earliest, of which several examples were found. One
was defined by an earthwork bank and is possibly medieval (nprn 510667). Another on
Banc Calc (nprn 510930) is egg-shaped and defined by boulders, and was superseded
by a large multi-cell fold built next to it (nprn 510929), which remains in excellent
condition, with walls standing to 1.6m high. But these round folds also have small cells
associated with them. One on Fridd Felen, which is well preserved, is 24m diameter but
had a small rectangular cell integral with it (nprn 510669). Likewise a fold on the east
side of <strong>Arenig</strong> <strong>Fawr</strong> (nprn 510847) is approximately 15m diameter on steep ground and
incorporates a rectangular cell 5m by 2.5m. It too appears to have been replaced, but
by a near square single-cell fold (nprn 510846).

Figure 11: Multi-cell sheepfold above Filltir-gerig (nprn 510966).
Sheepfolds are commonly found attached to the field walls, where they define the
upper limit of enclosed ground. Their origin is probably the eighteenth century, when
it is most likely that the field walls were constructed. Sheep creeps allowed sheep to be
passed from field to common. These are found throughout the survey area, for example
at Amnodd Wen farmstead (nprn 511065), above Fridd Uchaf at Blaen Lliw (nprn
511141, 511142), above Blaen-y-Cwm farm (nprn 510911, 510912) and on the north
side of Mynydd Nodol (nprn 510572, 51065).
Sheepfolds are also found in sheltered positions, often built against a natural rock
outcrop, for example on Banc Calc (nprn 510921), on steep ground below Carreg
Lefain (nprn 510721), and on high ground known as Y Castell (nprn 510732) at 683m
AOD.
Large multi-cell sheepfolds are comparatively late in the typology of such structures.
Their logic was that sheep were driven into the largest cell and then sorted into the
smaller cells, which corresponds with the interpretation that the ewes were brought
down from the mountain in spring. Sheepfolds of similar plan are still constructed,
although the materials are now posts with corrugated-iron sheet, or blockwork walls. A
disused example of the latter is at Hendre Blaen Lliw (nprn 511129). Some of the larger
sheepfolds were clearly the work of two or more phases. A good example is on Cefn
llwyn-y-bugail (nprn 510774). It consisted originally of two cells in a rectangular plan
12m long by 4m, to which a larger cell was added 11m by 7m, together with a guide
wall. Below Llyn <strong>Arenig</strong> <strong>Fawr</strong> is another multi-phase fold (nprn 510710). The earliest
part of the structure is a wall across the stream below the lake, suggesting a sheep
wash, to which a cell of drystone construction was added, followed in the twentieth
century by another cell defined by a post and wire fence. A similar case is at Afon
Llafar, which began as a sheepfold of two small cells measuring 7m by 6m, to which a
larger cell 11m by 7m with guide wall was added, followed in the twentieth century by
a fenced extension (nprn 510924).

Permanent farmsteads
There are permanent farmsteads in the Lliw valley and at Amnodd, all on the west side
of the <strong>Arenig</strong> <strong>Fawr</strong> ridge and all of them above 400m AOD. The highest is Amnodd
Wen (nprn 511409) at 451m AOD, where there is a succession of three farmhouses.
The earliest is a single-storey house with external fireplace, which was clearly an
addition (nprn 511016). The house is now roofless and its windows and doors have
been removed, but its roof slates have been carefully stacked as if in preparation for
reinstatement. This first house was replaced in the mid-nineteenth century by an
adjacent 2-storey house, now ruinous (nprn 511015). It stands on a substantial platform
retained by a stone wall facing the yard. In the 1890s a third house was added, also 2-
storey and now ruinous (nprn 511014). It was clearly one of a pair with Amnodd Bwll
farmhouse, described below. An outdoor privy in the retaining wall of the forecourt
probably belongs to this latter phase (nprn 511020). The farm buildings in the yard,
through which a track passes, belong to the later nineteenth century and are ruinous
(nprn 511013).
At Amnodd Bwll farm the house is the latest of the surviving buildings (nprn 511050). It
was built in the 1890s to the same design as Amnodd Wen farm, a 2-storey house of
rock-face stone, with casement windows, a roof of thin slates with barge boards, and
projecting back kitchen. With Amnodd Wen it clearly represents a substantial
investment in permanent farming in the nineteenth century. The house is uninhabited
but is still roofed and retains its windows and doors. Only one of the farm buildings in
the yard is roofed (nprn 511051), with thin slates, and is probably one of the buildings
shown on the 1838 Tithe plan. It was probably a cow house but it has external steps to
the loft.
Amnodd Bwll and Amnodd Wen were primarily cattle and sheep farms. Two features of
the enclosed pasture are the use of shelter walls and the use of the field cowhouse, or
beudy, which are characteristic of North Wales farms. Such buildings date at least from
the mid eighteenth century, were common in north Wales by the nineteenth century
and were described by Thomas Rowlandson in 1847: ‘the cattle are not all brought to
the homestead during the winter, but are housed in detached buildings at some
distance from each other, with a herdsman to look after each lot’ (quoted in Wiliam
1986, 89-90). According to Rowlandson they should be large enough to accommodate
up to eight cattle, and each has a small attached yard (fig 12). The yard contained the
haystack that was fed to the animals inside. Several of these buildings were found,
mostly unroofed but with the walls standing to near full height. All are above 400m and
the highest is at 485m AOD (nprn 511022). They are similar to other cow houses found
in north Wales (Wiliam 1986, fig 75a). In plan they measure 11m by 6m with walls
standing up to 1.8m high to the eaves, and some of them may have had lofts as there
are openings in the gables. Entrance was normally in the downhill gable end, which
facilitated mucking out. Another doorway opened into the hay yard. While the beudy is
well built (perhaps professionally) the attached yard walls are not integrated and are of
much rougher construction, like the example at Beudy y’r Cwm (nprn 511064). Where
roof structure has survived they can be seen to have sawn king-post trusses of the
nineteenth century. Only the roofless examples were therefore possibly built before
1800.
There are four cowhouses attached to Amnodd Bwll farm. The Ordnance Survey
indicates that two of them (nprn 511049, 511064) remained roofed and were
presumably still in use at the end of the nineteenth century, while the other two (nprn
15

511055, 511059) had been abandoned. Three cowhouses belonged to Amnodd Wen –
Beudy Nant-y-Pysgod (nprn 511022), Beudy Ty’n-y-Clogwyn (nprn 511009) and
another that may originally have been part of a separate holding (nprn 511008). Beudy
Ty’n-y-Clogwyn is large, 14m by 11m, requiring internal piers to support the roof, and
is of a later type, perhaps belonging to the same phase of farm improvement as the
latest of the houses. There are also sheepfolds within the enclosed ground (nprn
511066, 511068, 511012), as well as bordering unenclosed rough pasture (nprn
511065). One cow house (nprn 510977) was found that belonged to Filltir-gerig farm,
in an enclosed landscape where there are many sheepfolds (nprn 510960, 510970,
510971, 510980).

Figure 14: Abandoned farmstead below Moel Llyfnant (nprn 511085).
The pattern of permanent farmsteads and field cowhouses, with sheepfolds on the
higher ground attached to the upper limit of enclosed land, is repeated in the Lliw
valley. Hendre Blaen-Lliw (nprn 28488) is an eighteenth or early-nineteenth century
two-storey farmhouse with an attached cow house in line across the slope (although
the farmstead is conceivably older than the present house). It had a single field cow
house (nprn 51134) that was replaced in the late nineteenth century by another cow
house (nprn 41572) of conventional plan, with three doorways for muck and feed
passages, and a doorway at the rear. It also has a sheepfold on the higher ground of
Ffridd Castell (nprn 511135).
Blaen-Lliw Uchaf farmhouse (nprn 28173) is of the eighteenth or early nineteenth
century, and incorporates a walled garden (fig 12). The adjacent cow house (nprn
511152) is in line but not attached, which is an unusual arrangement. The farm had two
field cow houses (nprn 41574, 511157), of which the former remains roofed. The farm
also incorporates sheepfolds (nprn 511156, 511176) in the enclosed land, as well as
folds outer to the upper boundary of the farm (nprn 511141, 511142). The latter were
once part of a smallholding named Fotty (511171), which itself may have developed
from an earlier seasonal dwelling and which was converted to a sheepfold after the
house was abandoned.
Although the land use was mainly pasture, some land was given over to arable. Filltirgerig
farmstead lies largely within the survey area. In 1797 arable accounted for
approximately 25 acres (of 487 acres) and in 1840 it had 33 acres (of 415 acres)
(Thomas 1967, 233). In the 1838 Tithe survey Amnodd Wen had 46 acres of arable. This
is significant because later in the nineteenth century the original house was converted
to a mill (nprn 511016), presumably for grinding animal feed. Some associated features
remain, such as the head race (nprn 511017) and tail race (nprn 511018). The wheelpit
is 3m long by 0.4m wide, and a drive shaft from wheelpit to the interior remains in situ.
Decline of permanent occupation on the west side of <strong>Arenig</strong> <strong>Fawr</strong> ridge began in the
nineteenth century. Fotty may have been occupied into the early twentieth century. A
small farmstead on the lower slopes of Moel Llyfnant (nprn 511085) was abandoned by
the time of the 1830 Ordnance Survey (fig 14). It was probably a permanent farmstead,
17

although it may have developed from an earlier seasonal dwelling, and was easily the
highest farmstead in the locality at 565m AOD. Amnodd Wen and Amnodd Bwll were
abandoned in the twentieth century, while Hendre Blaen Lliw and Blaen Lliw Uchaf,
while not inhabited, are still farmed, having been amalgamated with other holdings.
Their latter-day use is similar to that of the hafotai that were retained as adjuncts to
upland farms, but were probably used on a daily basis, with return to the hendre every
evening (Longley 2006, 82). Blaen Lliw Uchaf was last used on a regular basis when
sheep shearing was undertaken at the farm by the farmer’s family and neighbours.
Some of the cowhouses remained roofed into the twentieth century, such as Beudy-r
Cwm (nprn 511064), while two in the Lliw valley remain in use, but in connection with
sheep rather than cattle. Beudy Uchaf at Blaen-Lliw Uchaf was used for sheep shearing
into the twentieth century, but this has been discontinued now that sheep are sheared
on a much larger scale.
Peat cutting
Evidence of peat cutting was found in many parts of the survey area. These belong to
the post-medieval period, until the latter half of the nineteenth century when
improved transportation allowed coal to replace this time-consuming and laborious
method of acquiring fuel. Wood was the main source of fuel in the medieval period but
by the seventeenth century, according to the researches of Edward Lhuyd, the main
source of fuel in Llanycil parish was turf (Owen 1975, 309). Many writers visiting
<strong>Merioneth</strong> in the eighteenth and early nineteenth century noted that ‘the peat bogs
produce turf of an excellent quality’ (Evans 1812, 892). Not all of these sources of peat
could be identified on the ground. For example, Banc yr Arian below the foot of
Mynydd Nodol is described as ‘turbary’ in the 1838 Tithe survey but there is no
evidence of cutting visible on the ground. Edward Pugh, writing in 1813, noted how
peat stacks were arranged in groups of 10-20, often in a line (Owen 1975, 318). Groups
of stacks were indeed found in the survey area on the level ground of Gwastadros and
nearby on the common by Hafod y Garreg. Evidence of the peat cuttings from which
the material derived was, however, elusive.
In two places neat rectangular areas of cutting can be related to specific farmsteads –
Cwm Tylo and Amnodd Bwll (nprn 511050). Several regular cuttings are uphill of
Amnodd Bwll farmstead (nprn 511027, 511028, 511030, 511031, 511032, 511033) and
are connected to it by a track (nprn 511026). Cutting on the hill above Cwm Tylo is
shallow, barely 0.5m deep, but several discrete areas were found (nprn 511340,
511341, 511343, 511344), 511345), although other areas identified by air-photo
mapping were not found. On the summit of Mynydd Nodol are extensive areas of
cutting (nprn 510660, 510661, 510662, 510664) connected to Pen-y-gelli and Tan-ymynydd
farms by tracks (nprn 510655, 511236 respectively) (fig 15). One possible peat
hut (nprn 510899) was identified, but otherwise no structures were definitely
associated with peat cutting, with the possible exception of the rough stone shelters
used by shepherds.
Most of the peat cuttings were small in scale, often of indeterminate extent, and found
on high ground (fig 15). For example, many peat cuttings were recorded on the east
flank of <strong>Arenig</strong> <strong>Fawr</strong> above 650m AOD, up to a maximum of 732m (nprn 510740). On
the west flank of <strong>Arenig</strong> <strong>Fawr</strong> peat cuttings were found on the 700m contour (nprn
511074, 511077) that were perhaps associated with a hut immediately below (nprn
511080), itself at 612m AOD. Another example was found on Moel Ymenyn where a
18

small hut (nprn 511398), probably used by shepherds, contained a fireplace,
immediately adjacent to which was a small area of cutting (nprn 511399).
Peat cutting at high altitude was noted by Thomas Pennant in the Vale of Mawddwy in
the 1770s:
The turberies are placed very remote from their dwellings; and the turf or peat is
gotten with great difficulty. The roads from the brows of the mountains, in
general, are too steep even for a horse; the men therefore carry up on their
backs, a light sledge, fill it with a very considerable load, and drag it, by means of
a rope placed over their breast, to the brink of the slope; then go before, and
draw it down, still preceding, and guiding its motions, which at times have been
so violent, as to overturn and draw along with it the master, to the hazard of his
life, and not without considerable bodily hurt (Pennant 1883, ii, 220).
The sledge was called a ‘glwyd-fawn’, or ‘hurdle’, and was about 5 feet (1.5m) long.
Other contemporary accounts describe the scars left in the hillside when the sledges
descended, but no evidence of these was recognised during the field survey. The use of
sledges does, however, explain why so few tracks are associated with peat cuttings and
a reminder that cuttings are not necessarily related to the nearest hut or farmstead.
3.4 Industrial sites
Manganese Mining
In the nineteenth century manganese was mined from the <strong>Arenig</strong> and Rhinog
mountains. Manganese was first sought in Wales as a component of bleaching powder,
to which end it was exported to Glasgow chemical works. Later in the nineteenth
century it became an important element in steelmaking, producing an alloy very
resistant to wear, in glassmaking, and in the glazing of ceramics (Down 1980, 5-7)
Around <strong>Arenig</strong> <strong>Fawr</strong> the veins of ore formed as infilling in the faults and fissures of the
rock, and have been found in veins nearly 2m wide, often in conjunction with quartz.
These veins dip steeply and are of limited extent, which explains why there are so many
small surface workings, especially on Mynydd Nodol. Outcrops consisted of oxidised
ores, mostly psilomelane, but unoxidised ores were also worked underground from
levels and shafts. Mynydd Nodol contained ores comprising up to 54% manganese
(Welsh ores were typically only 25%, which is low by international standards) but,
despite that, Edward Halse claimed in 1892 that manganese could not be worked
profitably at that time (Down 1980, 13-14, 51; Dewey and Dines 1923, 69).
It is unlikely that the manganese mines were ever especially profitable, given the
comparatively short life of mining activity and the succession of owners of the principal
area of exploitation, Mynydd Nodol. The Great Northern Manganese Company
operated the Mynydd Nodol mines 1867-71, but from 1877 to 1880 they were worked
by Manganese <strong>Royal</strong>, a company owned by former Mines Inspector Charles Herbert
Stokes, who owned several non-ferrous mines in west Wales. In 1885-6 the mines were
worked by Henry Hands, followed by Edward Mounsey & Co in 1897, J.A. Wylie 1898-
1900 and by G.A. Claughton in 1906 (Down 1980, 70). There are only patchy output
figures, but 33 tons was mined in 1867, 50 tons in 1868, 29 tons in 1885 and 2 tons in
1906 (Down 1980, 69).

Substantial evidence of manganese mining was discovered in four areas of the survey.
The most prolific is Mynydd Nodol, followed by Moel y Garth. Fewer remains were
found on Moel Llyfnant and Pistyll Gwyn. The earliest leases for manganese mining on
21

the Crown land in Llanycil parish occurred in 1823 (PRO LR 1/226), and the earliest that
specifically mentions Mynydd Nodol is for 1838 (PRO LRRO 13/66). Such agreements
are a declaration of intent rather than evidence of actual exploitation, and the most
intensive period of activity appears to have been from the 1860s to the 1880s, the peak
recorded output being in 1868 when 50 tons were mined on Mynydd Nodol. Despite
being of relatively recent date, and the fact the some of them were still active, there is
very little acknowledgement of these workings on the Ordnance Survey of 1888, which
makes no reference to workings on Moel Llyfnant or Pistyll Gwyn, and little reference
to mining on Moel y Garth. By the 1920s the workings were idle, underground
workings had mostly been blocked, although one level was accessible for a distance of
20 yards (18.3m) [probably nprn 510583] (Dewey and Dines 1923, 70).
Extensive remains are found on Mynydd Nodol. The evidence is mainly surface
workings, in the form of pits and trenches (known as ‘opencuts’ in 1923) (fig 16). In
addition there are two shafts (nprn 510580, 510620) and at least two underground
levels (nprn 510583, 510621), which can be identified as such because the sites are
protected by modern fences. One of the shafts was 43 feet (13.1m) deep in 1892
(Down 1980, 51). Some of the other surface workings are large, up to 50m long (nprn
510555) and may incorporate the entrances to underground workings that have been
blocked and obscured by backfill.
When it was removed the ore was stored in simple ore bins, which are open square or
rectangular structures, two of which were located on Mynydd Nodol (nprn 510587,
510522). Other buildings were found, although their function is not easy to interpret.
They probably include workmen’s shelters and possibly smithies, although no buildings
were found that contained hearths (nprn 510568, 510569, 510584). One building may
have housed a winding engine (nprn 510575), since it incorporates a rubble-lined pit
for a winding drum or flywheel. It appears to have been supplied with water from a
nearby pond (nprn 510574). There is little in the way of transport infrastructure. An
inclined plane (nprn 510582) has a platform at the upper end for a winding drum (nprn
510610). At the base of the incline is a track (nprn 510492) which was probably made
to cart the ore back to the road from Bala to Trawsfynydd. The track passes by <strong>Arenig</strong>
station on the Bala-Ffestiniog Railway, which opened in 1882 and may have handled
ore from local mines. Other paths (nprn 510491, 510492, 510498, 510611) were used
by workmen.
Edward Halse, who was employed as mine agent by Henry Hands, wrote in 1892 of
workings on a ‘smaller hill’ near <strong>Arenig</strong> <strong>Fawr</strong>, which probably refers to the mine at Moel
Llyfnant, which is otherwise not recorded. The mine entrance (nprn 511166) is in steep
ground just below the summit of Moel Llyfnant, at 708m AOD (fig 17). The entrance
leads into a short rock-cut tunnel, at the end of which is a plugged shaft said to have
been 100 feet (30.5m) deep, with ore taken from a level 250 feet (76.2m) long. From
the entrance ore was taken down a steep path (nprn 511167) to an ore bin or dressing
floor (nprn 511145). This was presumably disused by 1888 since it is mislabelled
‘sheepfold’ on the Ordnance Survey of that date. Other related sites include a
workmen’s shelter (nprn 511328) built against a natural crag.
Manganese was worked on Moel y Garth in the 1870s by Mr Collins, and included a
vein 6 feet (1.83m) wide, worked for a length of 100 feet (30.5m) and a depth of 60
feet (18.3m) (Down 1980, 51). Like Mynydd Nodol there is a large number of surface
workings on Moel-y-Garth, many of them on its steep northern slope and cut by a
modern vehicle track. At least one deep surface working appears to have been the
22

entrance to an underground level (nprn 511227), which has been exposed in one place
where a pit has collapsed (nprn 511231) (fig 18). Another, large backfilled pit (nprn
511197) was probably another, perhaps a shaft, as a path (nprn 511198) leads from it
to a large ore bin or dressing floor (nprn 511200). (The landowner has said that
underground workings were disturbed when a modern vehicle track was created.)
Other ore bins were found scattered across the hill, close to large opencast workings
(nprn 511219, 511229, 511242) (fig 19).
There are few visible remains of manganese mining at Pistyll Gwyn, where output may
never have been substantial. There are no Crown Grants that mention Pistyll Gwyn,
although according to Edward Halse, mine agent at Mynydd Nodol, manganese was
worked in the 1870s from a vein 4-5 feet wide (1.2-1.5m), with a 77.5-degree dip
(Down 1980, 51). Several small surface workings have been identified (nprn 510834-
510839), some of which may have been prospecting trenches, and a possible ore bin
(nprn 510840). Any underground workings have been obscured by backfill.
Other Industries
Llyn <strong>Arenig</strong> <strong>Fawr</strong> was adapted as a reservoir from 1830 by the Bala Water Works
Company. The dam was altered in 1864, but was altered again in the twentieth century
and is now of modern character (nprn 510707). The first pipeline was laid in 1879, but
the lines of two pipes can be traced on the ground (nprn 510698, 510699), leading to a
treatment works at Ty’n-y-cae (beyond the survey area) (Roberts 1995, 13).
There are comparatively few quarry sites within the survey area. Ample quantities of
field stone were sufficient for local building needs. Slate quarries belong to the late
nineteenth and the twentieth centuries, hoping to exploit the established market for
roofing slates. They are confined to the small areas where shale overlies igneous rocks
(nprn 510972, 510910). A quarry was begun on Ffridd y Gloddfa (nprn 510910),
probably in the early twentieth century. However it was quickly abandoned because it
did not yield slates of sufficient quality.
Opportunities for quarrying were increased after the Bala & Ffestiniog Railway was
built, a small section of which passed across the survey area. The railway was opened in
1882 and closed for traffic in 1961 – the immediate cause of its closure was the
flooding of part of the line to create Llyn Celyn reservoir. Granite quarrying near the
railway began in the last decade of the nineteenth century at Maen Grugog (nprn
511002) and at Clogwyn y Fran. The latter was massively extended in the twentieth
century and was excluded from the survey area (but see an outlying working, nprn
511246), although it is the largest of the <strong>Arenig</strong> Quarries. It was linked by tramroad
(nprn 510953) with another twentieth-century quarry site (nprn 510972), which was
extended over the road to the railway near <strong>Arenig</strong> Station. Electricity for these quarries
was provided by a generating station (nprn 510956), which stands close to the
tramroad. The brick building is now roofless and its walls are in a precarious condition.
No machinery survives, but a narrow wheelpit outside the building suggests that power
for the generator was provided by a double Pelton wheel. This was supplied by a
pipeline, of which stone piers survive (nprn 510957), and fed from two reservoirs (nprn
510958, 510959), one of which retains water. Quarrying here appears to have
outlasted the closure of the railway.

3.5 Recreation
Few sites can be attributed to recreational use, despite the fact that the area is
frequented by walkers, and from at least the mid nineteenth century trout were fished
for sport in Llyn <strong>Arenig</strong> <strong>Fawr</strong> (Lewis 1843, Llanycil). There is a stone shelter on the cairn
at Moel yr Eglwys (nprn 43852) and another close by built against an outcrop at 820m
AOD. These may have been the work of walkers. One hut (nprn 510720), in a relatively
inaccessible position on the south-west side of Llyn <strong>Arenig</strong> <strong>Fawr</strong> and hemmed in by
steep cliffs, might have been a hut used by fishermen. The nearby sluice house (nprn
510709) by the reservoir dam now performs a similar function as a bothy maintained by
the Mountain Bothies Association.
3.6 Use of aerial mapping
Mapping of archaeological features from aerial photographs was carried out by
RCAHM Wales prior to the commencement of the field project. The results were
incorporated on to digital maps that were used in the field for identification. In
addition, the location of entries in the National Monuments Record and the regional
Historic Environment Records were pinpointed on the maps.
Many site types were identified by this exercise, including huts and folds, peat cuttings
and mine workings. It identified most, but by no means all, of the linear features such
as relict drystone walls. However, in all other cases the number of sites identified by
aerial mapping was a small proportion of the total number of each type of site found.
This was especially the case with mining remains. Prospecting trenches are small and
are obviously not easy to identify from the air, but even among the larger workings
aerial mapping identified only some of those on west-facing slopes, but none of those
on the north side of Mynydd Nodol, and none of the numerous and significant mining
sites on Moel y Garth. Many sheepfolds still appear on Ordnance Survey mapping, but
aerial mapping identified only some of those that are not. In most cases these were
sites where there are significant remains, often where the walls remain to their full
height. Earlier sites, which can now be identified only as a line of stones on the ground,
were not found by aerial mapping. The same was true generally of the long huts.
Peat cuttings were identified by air-photo mapping, notably the group of large
cuttings near Amnodd Bwll farmstead. Peat cuttings associated with Cwm Tylo
farmstead were identified from aerial photographs but, partly because they are very
shallow and partly because the ground has been intensively grazed by cattle, not all of
them were identifiable on the ground. On Mynydd Nodol large areas of peat cutting
were recorded, but not quite matching the extent of cutting indicating by air photos.
3.7 Summary and statement of significance
The <strong>Arenig</strong> <strong>Fawr</strong> survey comprises 32 square kilometres of varied terrain between the
230m and 850m contours. It is mainly open moorland, with frequent boggy areas
where the ground is level, and has steep crags around the <strong>Arenig</strong> <strong>Fawr</strong> ridge, and
around the lesser peaks of Moel Llyfnant and Moel Ymenyn. It therefore has a
combination of poorly drained wastes, exposed high ground, but also sheltered slopes
conducive to settlement.
Very few prehistoric and Roman sites were uncovered. There are summit cairns on
<strong>Arenig</strong> <strong>Fawr</strong> and Cefn Coch, while another site on Moel y Garnedd is doubtful, the
24

existence of a cairn here possibly suggested by the place name. Peat formation, which
is extensive throughout the survey area, may well have masked other prehistoric
features. A road that skirts the southern boundary of the survey area has previously
been interpreted as part of a prehistoric route across the <strong>Merioneth</strong> uplands to the
coast. A Roman road between the auxiliary forts of Caer Gai and Tomen-y-mur passes
across the survey area at Blaen Lliw, although evidence for it is slight and less
convincing than it is further west beyond the present survey area.
Settlement and agriculture of the medieval and post-medieval period dominates the
archaeology of <strong>Arenig</strong> <strong>Fawr</strong>. That the uplands were exploited for sheep and cattle
grazing in the medieval period can be inferred from documentary evidence. Medieval
townships stood near to the present limit of upland pasture, while at Boch y Rhaeadr
there was a grange of Basingwerk Abbey, and at Amnodd was one of the royal
hafodydd of Penllyn. Direct physical evidence of medieval pasture, however, is
confined to a substantial boundary bank above Blaen Lliw.
There is more direct evidence of medieval settlement on the uplands. Building
platforms and long huts occur frequently, especially in the areas sheltered by high
ground, such as the east side of the <strong>Arenig</strong> <strong>Fawr</strong> ridge, the east side of Moel Llyfnant
and the north side of Mynydd Nodol. Only two building platforms were identified that
did not have a structure upon them. Long huts can be difficult to distinguish from folds,
but where they stand on platforms or ledges they have been interpreted as dwellings.
The earliest, of medieval date, are those with rounded end walls, and are generally
small, only approximately 8m by 5m. This type of dwelling was also built in the postmedieval
period. The later examples have square end walls, and at least three of them
have fireplaces.
Enclosure in the post-medieval period also altered the character of the landscape.
Fridd place names are common and refer to rough pasture that has been enclosed,
often illegally, which has shrunk the extent of common land. This process appears to
have been completed by the eighteenth century.
Permanent occupation of higher ground above 400m continued into the twentieth
century at Blaen Lliw and Amnodd. These have a landscape of dispersed farmsteads
with field cow houses, the latter almost certainly being no earlier than the late
eighteenth or early nineteenth century. Some of the fields were devoted to arable, and
an old house at Amnodd Wen was converted to a small grist mill in the nineteenth
century. Around the edges of the farmsteads are sheepfolds, which are the most
common form of farm structure found on the uplands.
Some sheepfolds are circular and may be the earliest type. Later examples are larger,
multi-cell structures, often the result of enlarging an earlier fold. Sheepfolds are found
attached to the upper limit of enclosed ground, where they had an obvious function in
the movement of sheep between upland and lowland pasture. Others are small
structured scattered over the uplands, especially on common land, and often built in
sheltered positions against exposed bedrock. Small shelters for use of shepherds are
often found nearby.
Peat was one of the principal resources of the uplands from the seventeenth century to
the end of the nineteenth century. A large number of peat cuttings was identified,
occasionally with associated tracks that can be linked with specific farmsteads. Most
cuttings, however, were small and of a traditional upland type where peat was
25

exploited from high ground and transported down by means of sledges to the nearest
road or track. These cuttings survive usually in a fragmented form, but were
characteristic of the <strong>Merioneth</strong> upland landscape in the eighteenth century where peat
cutting attracted the notice of travelling writers such as Thomas Pennant.
Manganese ore is found close to the surface on the <strong>Arenig</strong> mountains and evidence of
manganese mining was found in four places within the survey area – Mynydd Nodol,
Moel-y-Garth, Pistyll Gwyn and Moel Llyfnant – that belongs from the 1860s through
to the early twentieth century on Mynydd Nodol. The relict mining landscape of
Mynydd Nodol has a distinctive character, even among other landscapes of manganese
mining in North Wales, because of the particular geological nature of the <strong>Arenig</strong>s,
where the ore was found in small pockets that could be exploited on the surface. It has
meant that the landscape is littered with small opencast workings and prospecting
trenches. A similar landscape but on a smaller scale is found on Moel-y-Garth, where
mining began in the 1860s but had ceased by the 1880s. Moel Llyfnant and Pistyll
Gwyn have mining remains on a much smaller scale, but at Moel Llyfnant is a coherent
narrative of manganese mining in the form of exploratory trenches, underground
working, ore processing facility and transport system.
Other industries are represented only in a minor way. Llyn <strong>Arenig</strong> <strong>Fawr</strong> was adapted as
a reservoir in 1830 and is one of the earliest large reservoirs in Wales. A small amount
of slate quarrying, and larger-scale granite quarrying, belong to the late nineteenth
and twentieth century. The latter was made viable by proximity to the Bala and
Ffestiniog Railway, which opened in 1882.
4.0 Recommendations
Several buildings were recorded during the survey, of which Blaen-Lliw-Uchaf (nprn
28173) may qualify for listed-building status. It has an adjacent cow house (nprn
511152) and field cow house known as Beudy Uchaf (nprn 41574), which are both
roofed and may be worth listing for group value with the house. Hendre Blaen Lliw
(nprn 28488) retains its traditional character, despite modern replacement of its
windows and a new slate roof. Other dwellings are of considerable interest, such as the
earliest house at Amnodd Wen (nprn 511016), but it is roofless and in too ruinous a
condition to qualify for protected status.
No threats to the archaeological resource are known, in a landscape that is already
protected for its wildlife and habitats, and where much of the land is under Tir Gofal.
Peat deposits that may be suitable for pollen analysis and other environmental
sampling are found across the survey area. The east side of <strong>Arenig</strong> <strong>Fawr</strong> is the area that
has the greatest concentration of settlement sites, and peat deposits are regularly
found here 1m deep, for example near Pistyll Gwyn (in the vicinity of SH 842 367).
There are also peat deposits at the foot of Moel Llyfnant, near the headwaters of Afon
Amnodd Bwll and Afon Erwent (approximately SH 815 350), where there is also
significant settlement. In both of these areas there has been significant peat cutting,
however. An area relatively free from peat cutting is on the west side of the survey
area, between Cefn Glas and Nant-y-Gistfaen (in the vicinity of SH 795 368), but there
has been little settlement here.
26

Knowledge and understanding of manganese mining around <strong>Arenig</strong> <strong>Fawr</strong> would be
enhanced by a more detailed field survey. As stated above, Mynydd Nodol is a relict
mining landscape of distinctive character, which includes shafts and levels, but also
numerous opencast workings and prospecting trenches, and it is likely that some
additional smaller features would be revealed by detailed work that have not been
identified by the present rapid survey. Moel-y-Garth also has significant remains that
would benefit from detailed survey in a similar way. Evidence of mining on Pistyll Gwyn
is slight, perhaps partly because of backfilling of workings, although mining here was
never a substantial operation. Nevertheless it would benefit from more detailed survey.
It is unlikely that additional sites would be revealed on Moel Llyfnant but a detailed
survey would make sense of a micro industrial landscape which has evidence of
prospecting trenches, underground working, transport system and ore processing.
Modern Ordnance Survey maps show some prehistoric sites, but otherwise have no
other archaeological features, although many huts and folds are mapped as
topographical features. Other sites that should be appended to Ordnance Survey maps
are given in table 4.
