Crynodeb Nad yw’n Dechnegol 

Gwnaethpwyd arolygiad o ardal <strong>Mynydd</strong> <strong>Llangynidr</strong> o dan nawdd Menter Ucheldiroedd 

gymorthedig y Comisiwn Brenhinol ar Henebion Hanesyddol Cymru (RCAHMW) rhwng Ebrill 2008 

a Mawrth 2009. 

Oddeutu 38 cilomedr sgwâr oedd maint yr ardal arolygu ac roedd yn cwmpasu crib i’r Gogledd o 

Ferthyr Tudful ac i’r Gorllewin o Grucywel, gyda Chronfa Pontsticill yn ffin iddi i’r Gorllewin a’r 

B4560 yn darparu’r ffin Ddwyreiniol. I’r de gorweddai terfyn y Parc Cenedlaethol, Comin Merthyr 

a’r A465 (T) rhwng Cendl a Merthyr Tudful. 

Cafwyd 660 o safleoedd o ganlyniad i’r arolygiad, ac o’r rhain yr oedd 121 wedi’u cofnodi ar y 

NMR a 320 ar yr HER. Roedd gan yr ardaloedd dyffrynnog ddwysedd uwch o safleoedd na’r 

llethrau uwch. Roedd hyn oherwydd bod llawer mwy o graig yn brigo y medrid ei defnyddio er 

mwyn codi adeiladweithiau. Gwelwyd gweithgarwch diwydiannol mynych ôl-ganoloesol a modern 

o amgylch ymylon yr ardal arolygu, yn arbennig yng Ngogledd-ddwyrain a De-orllewin yr ardal. 

Ni chafodd y pantiau o waith dyn a gafwyd yn aml iawn yn y llethrau marian eu cofnodi bob 

amser, oherwydd iddynt gael eu hadeiladu’n ddiweddar iawn ac am fod cymaint ohonynt yn 

gyffredinol. Nodweddion ôl-ganoloesol neu fodern oedd y rhain a grëwyd gan dynnu cerrig rhydd 

a’u pentyrru o amgylch y pant. Fel rheol yr oeddent oddeutu 1.5 medr ar eu traws ac 1 fedr o 

ddyfnder, er bod eu siâp a’u maint yn amrywio’n sylweddol. Fe’u ceid yn aml mewn grwpiau, 

weithiau bob yn ddau, ond yn ddigon mynych yn dod i gymaint â deg neu bymtheg. Mae’n 

ymddangos bod y pantiau hyn yn llochesau bach neu dyllau ymochel, sy’n gysylltiedig â 

hyfforddiant milwrol. Golyga’r ffaith fod cymaint o’r nodweddion hyn yn bresennol ledled yr ardal 

na chawsant mo’u cynnwys yn y gronfa ddata derfynol. 

Yn gyffredinol cafwyd y cerrig brig ar y llethrau uwch, ac arddangoswyd argaeledd calchfaen ar 

gyfer adeiladu a phrosesau diwydiannol gan yr odynau calch a’r chwareli yn yr ardal arolygu. 

Yn ystod yr arolygiad ni lwyddwyd i ganfod rhai safleoedd a gofnodir yn yr HER lleol 

(Ymddiriedolaeth Archeolegol Clwyd-Powys). Mewn rhai achosion, medrai hyn fod oherwydd bod 

y cyfesurynnau yn anghywir. Mwy na thebyg y gellir priodoli methiannau eraill i ddod o hyd i 

safleoedd i’r gorchudd trwchus o lystyfiant ar y llethrau is a’r ardaloedd eang o weunydd mawn a 

chorsydd yn rhan ddeheuol yr ardal arolygu. Gallai’r tywydd fod yn ffactor yn ogystal, gydag eira 

ysgafn yn cuddio rhai nodweddion o bryd i’w gilydd. Fodd bynnag, daethpwyd o hyd i lawer o 

safleoedd newydd yn ogystal. 

Yn gyffredinol, llwyddodd y prosiect yn y gwaith o greu cofnod cyflawn o’r adeiladweithiau 

artiffisial o fewn yr ardal arolygu a chynhyrchu set o ddata a fydd yn cefnogi ymchwil yn y 

dyfodol. Defnyddiwyd cryn dipyn ar GIS a bydd y trawsgrifiadau o’r ffotograffau o’r aer o’r 

RCAHMW a’r data yn cyfrannu at brosiect sydd ar y gweill yn ArchaeoPhysica er mwyn datblygu 

dulliau dadansoddol wedi’u seilio ar GIS o archwilio Ucheldiroedd Cymru.

Non-Technical Summary 

Survey of <strong>Mynydd</strong> <strong>Llangynidr</strong> area proceeded on the auspices of the <strong>Royal</strong> <strong>Commission</strong> on the 

Ancient and Historical Monuments of Wales (RCAHMW) grant aided Uplands Initiative between 

April 2008 and March 2009. 

The survey area was roughly 38 square kilometres and covered a ridge north of Merthyr Tydfil 

and west of Crickhowell, bounded by Pontisticill Reservoir to the west and the B4560 to the east. 

To the south was the National Park boundary, Merthyr Common and the A465 (T) between 

Beaufort and Merthyr Tydfil. 

The survey resulted in 660 sites, of which 121 were recorded on the NMR and 320 on the HER. 

The valley areas bore a higher density of sites than the upper slopes. This was because there 

was far more outcropping rock which could be utlised to build structures. There was frequent 

post-medieval and modern industrial activity around the edges of the survey area, particularly in 

the north-east and south-west of the area. The very frequent occurrence of man-made hollows in 

the scree slopes were not always recorded due to their very recent construction and overall 

abundance. These were post-medieval or modern features created by removing loose stones and 

piling around the depression. They were usually about 1.5 metres across and 1 metre deep, 

though their shape and dimensions varied markedly. They were often found in groups, 

sometimes in pairs, but not infrequently numbering as many as ten or fifteen. It seems that 

these hollows are small shelters or foxholes associated with military training. The number of these 

features all over the area meant that they have not been included in the final database. 

The rock outcropping was generally on the higher slopes and the availability of limestone for 

building and industrial processes was demonstrated by the lime kilns and quarries in the survey 

area. 

Some sites recorded in the local HER (the Clwyd-Powys Archaeological Trust) could not be found 

during survey. On occasions this could be because the co-ordinates were incorrect. Other failures 

to locate sites are probably attributable to the dense vegetation cover on the lower slopes and the 

large areas of peat bogs and marsh in the southern part of the survey area. Weather conditions 

may have also been a factor, with light snowfall sometimes masking some features. However, 

many new sites were also discovered. 

Overall the project has been successful in making a total record of the artificial structures within 

the survey area and producing a data set that will support future research. Extensive use has 

been made of GIS and the air photo transcriptions from the RCAHMW and the data will contribute 

to a developing project at ArchaeoPhysica to develop GIS-based analytical approaches to 

examining Welsh Uplands.

1.1 The survey area lies within the Brecon Beacons, Powys, and covers roughly 35 square 

kilometres over one ridge, <strong>Mynydd</strong> <strong>Llangynidr</strong>, west of Crickhowell, and Cefn yr Ystrad, east of 

Pontsticill reservoir and north of Merthyr Tydfil. 

Parties involved 

1.2 The survey was commissioned by the <strong>Royal</strong> <strong>Commission</strong> on the Ancient and Historical 

Monuments of Wales (RCAHMW) on receipt of grant aid funding from the Welsh Assembly. 

1.3 Fieldwork used a team of up to five people drawn from Anne & Martin Roseveare, Graham 

Britton, Neil Paveley and Graham Arnold. Database design and GIS support was by Martin 

Roseveare and data entry was by Graham Arnold. GIS-based analysis was by Martin Roseveare. 

1.4 Acknowledgements are due to the RCAHMW for support during the project, CPAT for supply 

of information from the HER, Welsh Water (Dwr Cymru) for allowing access to their tracks leading 

to reservoirs and the Forestry <strong>Commission</strong> for allowing access to their tracks. 

Basic methodology & rationale 

1.5 The Uplands Initiative projects are field reconnaissance exercises contributing to an increased 

understanding of the archaeological content of the Welsh upland regions. 

1.6 A GIS system was prepared in advance, incorporating current mapping (OS Landline), a 

digital elevation model (OS Landline Profile), desktop assessment results and known sites from 

the NMR, HER and the RCAHMW air photo mapping project. 

1.7 Transects were walked at between 30m and 50m intervals depending upon local visibility and 

accessibility. Sites are recorded using a standard written format and hand-held GPS units. Checks 

are made in the field against those sites already known, including RCAHMW air photo mapping. 

Constraints & variations 

1.8 The start of the main fieldwork was in December 2008 and finished in March 2008. Heavy 

snow and frequent fog halted the survey. The unexpected discovery of a very high density of 

hollows in the rock outcrops, attributed to the military as shelters or foxholes and industrial 

quarries caused the survey to be conducted in two in order to catch up on entering the escalating 

amount of data on to the database. 

1.9 With one or two exceptions the entire area was walked with a mean line separation of 

between 30m and 50m as required by the specification. The exceptions to this were for reasons 

of safety on extremely steep slopes. Where this was the case, a visual assessment from the top 

and bottom of the slope and from adjacent accessible slopes was made. In most, if not all cases, 

the very steepness of these slopes would preclude significant past human activity.

2.2 From experience of working in the higher mountains of Wales, non-OS historic mapping has 

not been consulted due to difficulties in determining the location of depicted features on the 

ground. This is because the precision of the original mapping is obviously unknown but also the 

lack of landmarks makes attempts to georeference the material to modern mapping at best 

inaccurate. This in turn leads to uncertainty in the field, avoided by simply mapping all artificial 

structures during fieldwork. 

2.3 Other sources were examined and the principal ones are listed below: 

Clwyd-Powys Archaeological Trust HER extract 

Clwyd-Powys Archaeological Trust website (HLC studies, previous work, etc) 

Countryside Council for Wales website (background information) 

BGS 1:625,000 Bedrock Geology 

Megalithic Portal website (background information) 

Page 2 







National Soil Resources Institute http://www3.landis.org.uk/soilscapes/ 

National Monuments Record of Wales (NMRW) extract 

RCAHMW Coflien 

RCAHMW Uplands Project air photo transcriptions 

Rob Evans’ compilation of aircraft crash sites 

Assessment and compilation 

2.4 The NMR data for the survey area contained 121 records, of which twenty are Scheduled 

Ancient Monuments. A high proportion of the NMR records in some areas were recently updated 

by Uplands survey or similar fieldwork, with good location information and descriptions, but were 

monuments unknown as yet to the HER. 

2.5 The HER data contained 320 records within or immediately adjacent to the survey area. The 

description field in the HER was truncated for some entries due to the export format used by 

CPAT. 

2.6 It was sometimes not possible to locate sites on the HER record. This could be because, as 

has been found previously, multiple records in the HER are in fact the same monument – 

transcribed from various epochs of early OS mapping with slightly different positions. From 

discussion at the Uplands Forum February 2007 it was apparent this is a known occurrence (Bob 

Sylvester, pers. comm.). Some failures to locate sites could be explained by changes in conditions 

such as vegetation cover. 

2.7 In several cases HER records were found to be vague, occasionally wrong or incorrectly 

located; those by Palmer and Jones have in particular been found to warrant care in their use, 

quite often due to their failure to adequately differentiate between nearby monuments. 

2.8 The 1st – 3rd Epoch OS maps were assimilated into the project GIS as georeferenced images, 

then all monuments, sites and former tracks & boundaries transferred to the initial sites record 

ahead of fieldwork. Where features existed on more than one epoch of mapping, the latestmapped 

position of the feature was taken. 

HER data 

2.9 The HER data for this area proved to be of abnormally low quality for a variety of reasons. 

One major issue that emerged late in the project is that the quality of the position stated in many 

of the records is open to question and this appears to have resulted in successive episodes of 

fieldwork appending to the record rather than updating content. As a result, it has proved 

extremely difficult and occasionally impossible to be sure exactly which HER record applies to any 

given monument or locality in the field. 

2.10 Second, having battled through this, it has become evident that some previous episodes of 

fieldwork have resulted in very different quality records. While this is inevitable in an 

accumulating record, the situation becomes grave when the same monument is comprehensively 

but differently described in each record. This extends beyond the description to monument type 

classifications and hence the process of matching HER records to Uplands fieldwork records has 

proved an abnormally long-winded and convoluted affair. 

2.11 The number of records in the database with form stated as ‘documents’ is proportionally 

larger than usual; to avoid their loss any that appear to be describing a locatable monument have 

been included. The certainty of them being associated with their stated position is, however, low.

Field survey 

Dates & personnel 

2.12 Fieldwork ran from February 2008 through to the beginning of March 2009. A number of 

days were partly or completely lost due to adverse weather conditions. 

2.13 The entire personnel were drawn from ArchaeoPhysica Ltd. Within each team there was a 

nominated First Aider and a mixture of people with varying experience. Graham Arnold oversaw 

health and safety and was responsible for data collection and collation procedures. 

Equipment 

2.14 Each field team carried cameras and GPS units and each walker had a waterproof notebook 

and a laminated booklet of templates to guide recording. Detailed maps depicting known sites 

and all landscape details were carried. 

2.15 Individuals provided their own appropriate clothing. High visibility vests/jackets were worn 

and mountain safety gear and first aid kit were spread amongst the team members. 

Technique 

2.16 The vast majority of the survey area was unenclosed heath and subsequently the open 

mountainside was surveyed according to the topography, e.g., a side of a valley at a time. 

Coverage was monitored daily and no significant omissions were found. In areas of open 

grassland and peat bogs, traverses were up to 50m apart if there was sufficiently clear visibility. 

2.17 Through previous experience it was known to be necessary to work with the landscape at 

all times to avoid undue exertion. For this reason fieldwork usually worked along the contours 

wherever possible, starting at the base of slopes and working uphill until about midday and then 

returning downhill in the next swathe of country. In the low lying areas of thick marsh and peat 

bogs care was taken to ensure that they were passable safely. 

2.18 For safety reasons the fording of streams was avoided wherever possible, these being used 

to bound survey areas instead. 

2.19 There were no reportable or non-reportable injuries or near miss incidents. 

Records 

2.20 The overall rationale behind the formation of the record was to ensure the basic 

information was captured efficiently in the field, whilst allowing checking of previously known 

sites. As for previous surveys the emphasis was on the collection of a total record regardless of 

whether a monument had been previously described. 

2.21 Record sheets carry the identity of the author and the date of survey to enable auditing, 

along with GPS unit ID and way-mark number as well as the recorded co-ordinates. 

2.22 Record fields such as ‘Broad Class’, ‘Form’, ‘Condition’ and ‘Land Use’ were completed from 

lists of permitted field contents to minimise the chance of ambiguous records, using a template. A 

sketch of the monument was required where complex or unusual shapes or layouts existed. This 

was usually the case within quarry sites and composite sheepfolds. 

2.23 In general one photograph was taken of each site, the exceptions being where more than 

one view of a site was felt necessary or where multiple sites appear on photographs. Occasionally 

poor light and other conditions prevented a photograph from being taken. Photographs were not 

always included in the case of the modern hollows dug into the scree slopes or modern quarries 

that had recently gone out of use. 

2.24 Monuments within complexes were allocated ad hoc between team members with internal 

specialisms brought to bear. Larger complexes were recorded within specific field campaigns to 

avoid accidental omissions or duplicates. 

Page 4 







2.25 Find spot locations were checked for possible further remains although the precision of 

these meant that any further finds were likely to be accidental. No further finds were found at any 

of the given locations. 

Archive considerations 

2.26 The result of the field campaign is a set of waterproof notebooks. These are the original 

records, each record in which carries a unique ‘EN’ number. 

2.27 These records contain occasional sketches of sites, and therefore include more information 

in some cases than can be conveyed in the written record. However, they also represent the 

original primary record whereas the digital record contains corrected, augmented and updated 

data and therefore has precedence. 

2.28 In addition, there is a photographic archive in digital form and the NMR-compatible flat 

database required by the RCAHMW specification. Additional photographs showing general 

landscape views are contained in our archive. 

Data collation & analysis 

2.29 The basic digital record was built in stages as the survey proceeded, permitting errors and 

queries to be caught in good time and reviews or repeat visits made where required. 

2.30 In each batch of data entry all records were given a unique ‘EN’ number as a temporary 

analogy to the NPRN to enable auditing. Each record was checked for omissions and obvious 

errors before being passed for initial data entry into the database. 

GIS formation 

2.31 To aid fieldwork planning and logistics in detail the database content was available as a live 

layer in the project GIS throughout survey. All monuments already recorded within the NMR, the 

local HER, the AP mapping and those available from the desktop study were also available as GIS 

layers and the whole superimposed upon topographic mapping (OS Landline) and an elevation 

model (OS Landform Profile). To this was added access information, e.g., CRoW access/nonaccess 

land, negotiated access and other restrictions. 

2.32 In addition, a full virtual landscape was formed by draping detailed colour aerial 

photography onto the digital topographic model and overlaying this with streams, monument 

locations etc. The GIS then permitted ‘fly-throughs’ to be performed with considerable logistical 

and practical benefit. 

2.33 The area covered was recorded each day within another layer. With this it was possible to 

correlate the rate of coverage with the density of monuments and the type of terrain and hence 

predict fairly accurately how much ground could be surveyed from one day to the next. It also 

allowed for the planning of escape routes and identification of hazardous areas during the 

allocation of survey blocks. 

2.34 For all records altitude data was transferred automatically into the record from a surface 

generated from OS Landform Profile data. 

2.35 Where NMR or HER sites were records of multiple related monuments, the relevant parts of 

the information were combined with individual site records. The NMR record was often used as 

the “parent” record for a complex, with “child” records being formed from information from field 

survey and the other sources. 

Limiting factors 

2.36 The visibility of low-lying monuments in peat country is severely limited by the presence of 

the peat itself and by the dense heather growth topping it in most places. The slopes of the 

survey area suffered thick heather growth. An additional complication with this survey was several 

falls of snow during the fieldwork. 

Page 5 







2.37 The improved fields within the survey area have associated clearance cairns and piles of 

dumped stone. However, some of these may conceal earlier sites, such as prehistoric funerary 

monuments. 

2.38 Many of the hilltop cairns have had shelters built on them, masking the form of the earlier 

monument. 

2.39 The Brecon Beacons are the scene of current military training. Evidence of this (in the form 

of shelters and hollows) was found during the survey. Personnel and ammunition may therefore 

have damaged and obscured earlier monuments. Sites that were obviously very recently made 

were omitted from the final database due to the sheer number, specifically on the eastern side of 

<strong>Mynydd</strong> <strong>Llangynidr</strong>, close to the B4650 where training was frequently taking place during the 

survey.

3 Context 

Physical landscape 

Landscape form 

3.1 The survey area includes two ridges aligned roughly east-west. <strong>Mynydd</strong> <strong>Llangynidr</strong> to the east 

and Cefn yr Ystrad to the west. The bulk of the area is formed from a mass of Carboniferous 

limestone topped with a small amount of Millstone Grit and the whole bedded upon Old Red 

Sandstone. 

Soils and vegetation 

3.2 The area is characterised by slowly permeable wet very acid upland soils with a peaty surface. 

The vegetation is moorland and heath with rough grazing and a little forestry. Valley bottoms 

tend to have dense carpets of old heather punctuated by areas of open stony ground, some of it 

evidently till deposits. 

3.3 The lower slopes of the survey area have thick bracken cover which gives way to heather and 

then short, unimproved grassland on the tops. There were rocky outcrops around the tops of 

<strong>Mynydd</strong> <strong>Llangynidr</strong>. There were some improved fields in the northwestern corner of the survey 

area, close to Pontsticill reservoir which were pasture. There was also some woodland around the 

borders of the area. 

Hydrology 

3.4 The streams that flow down the northeastern slope of the survey area feed into the Dyffryn 

Crawnon in the valley bottom. The slopes towards the south of the area, below <strong>Mynydd</strong> 

<strong>Llangynidr</strong> and Cefn yr Ystrad are particularly wet. Upon the plateaux there were areas of peat 

and standing water, but at the time of survey they were not impassable. The Pontsticill Reservoir 

is adjacent to the western boundary of the survey area and smaller reservoirs are located in the 

southwestern and southeastern corners of the survey area. 

3.5 The limestone areas are densely populated with sinkholes of variable size and a number of 

caves are known within this material (the Chartists’ Cave being a famous example).

4 Field Survey 

Introduction 

Use of GIS 

4.1 At the analysis stage of the project GIS has been used to automate several labour-intensive 

tasks and to provide a powerful platform for spatial analysis. The data preparation tasks for which 

GIS was used include: 

• Matching of surveyed monuments with existing NMR & HER records by location, including 

morphing of HER tables into NMR format 

• Identification of monuments not found during survey by location 

• Automated insertion of community and other regional details into the record 

• Capture of height data from the OS DEM 

• Automated extraction of OS features and map generation 

• Generation of an environmental model to assist with the provision of landscape context 

• Fusion of NMR, HER, survey, aerial photographic and OS-derived data for analysis 

• Database management, NPRN enumeration and table linking, etc. 

• Exploration of thematic landscape encoding to faciliate mathematical analysis of site location, 

etc. 

4.2 The thematic zoning is currently being developed and at the moment consists of the survey 

area divided into 100m x 100m cells, each with an average height, slope, aspect and distance 

from water. Vegetation cover is being added, based upon the fieldwork, as will be soil type. 

Between these, there should be sufficient information to examine what relationships exist 

between the presence or absence of monuments, their location and type and situation. Initial 

observations suggest strong correlations do exist but whether they can be generalised and turned 

into a reliable predictive model has not yet been examined. 

4.3 In addition, all of the analyses described below were conducted within the GIS for simplicity 

and to use the implicit spatial structure of the data to best advantage.

5 Discussion 

Survey 

Coverage 

5.1 All the area originally allocated was covered. Coverage rates varied depending on terrain 

which varied from pasture to steep rocky slopes and heather-topped peat. Poor weather on some 

days also slowed progress as would be expected in this sort of environment. 

5.2 The partly-eroded peat deposits and vegetation may have masked features. However, the 

peat was sufficiently deep to be ancient in its own right and therefore has significant palaeoenvironmental 

potential, especially in the southern part of the area (e.g. Pen March). 

Significant discoveries 

Land usage 

5.3 The dominant current land use is sheep grazing, shooting and open heath land. There are 

grouse on the mountain tops and shooting butts were frequently observed. Some of the lower 

slopes of the open mountain side, particularly west of Cefn yr Ystrad had clearance cairns 

indicating that the land was once improved and has since been abandoned. There were a handful 

of improved fields and a small amount of woodland around the edges of in the survey area too. 

Settlements 

5.4 The most widespread settlement was recorded at the bottom of the slopes to the south of 

<strong>Mynydd</strong> <strong>Llangynidr</strong> at SO 31400 16500 and SO 14800 16100, a sheltered valley above a large 

stream, on the east and west sides of forestry. Another similar settlement was also recorded at 

the source of the stream on the north-facing slope of Carn Caws It comprised several long 

houses and huts and perhaps represents several periods of occupation, the earliest perhaps being 

medieval. 

5.5 Shepherd’s huts were usually found close to sheepfolds or enclosures, although some were 

found in isolation. Huts were occasionally found within or adjacent to quarries as well, or close to 

limekiln activity. 

5.6 Prehistoric settlement included hut circles on the upper south-facing slope of Waun Rydd 

valley, on the eastern side of a stream, though these were not the only examples. Prehistoric 

occupation of the area was also indicated by the presence of cairns. Large cairns were located on 

the summit of Carn Caws, <strong>Mynydd</strong> <strong>Llangynidr</strong> and Cefn yr Ystrad and these are sufficiently large 

to have been exploited later on as shelters, with hollows being dug into the centre. A similar 

large and mutilated cairn was located on the ridge to the south of Cwm Nant-y-fedw at SO 20119 

26071. Examples of low barrows were recorded on <strong>Mynydd</strong> <strong>Llangynidr</strong> and Waun Rydd, with 

some examples heavily overgrown and turfed over. 

Quarrying 

5.7 Areas of quarrying were recorded throughout the survey area and at all heights, but more so 

towards the tops of the ridges, where natural limestone rock outcrops. The form of quarrying 

was mostly scoops cut laterally into the outcrop, with subterranean quarrying absent in the survey 

area. There were several disused modern quarries around the edges of the survey area, 

demonstrating the industrial heritage of the area. Most quarries recorded were undateable, but 

seem to relate to post-medieval activity. The larger complexes, sometimes a hundred metres 

across, were often located close together to exploit a particular section of rock and were 

accompanied by tracks and buildings. A good example of this is around Blaen Onneu at SO 

15500 16800, where several widespread areas of quarrying occupy the same ridge, forming 

prominent landscape features. 

Page 12 







Tracks 

5.8 The vast majority of the tracks found were fairly modern and provided access to the quarries. 

Other tracks were caused by modern agricultural activity and walkers’ access to local attractions 

such as the Chartist’s Cave at the centre of <strong>Mynydd</strong> <strong>Llangynidr</strong>. These were not recorded as they 

were usually too modern to warrant a specific record. Many tracks are heavily obscured by 

vegetation and there were a variety of forms. Some were revetted with stone walling either 

downslope or upslope, some were simple ledges cut into the hillside or embanked upon it, and 

many were hollow ways. Of the latter many were faint depressions, but some were impressive 

cuttings as at SO 19197 24939, where the trackway is roughly 2 metres deep and 3 metres wide 

at the top of the hollow. A few tracks, particularly along the tops of the ridges, are still used by 

walkers due to the views, and for the same reason may date back thousands of years. These 

tracks are usually simple worn paths ranging for kilometres and are frequently marked with 

cairns. 

Sheepfolds 

5.9 Sheepfolds were scattered throughout the area, varying markedly in size and shape. A 

complex one including a 50 metre long central cell with four other cells inside was located at SO 

09667 011984. The amount and quality of construction suggests it was once an element of a 

centralised system of sheep management with perhaps several owners sharing the resource. 

Recreational and clearance cairns 

5.10 Most of the cairns recorded were associated with trackways, and probably date to the post 

medieval period. Several of the summits in the area had piles of stones made by modern day 

walkers. Recreational cairns were also found within defunct quarries where there was plentiful 

waste material and around collapsed walls. The distribution of recreational cairns therefore 

correlates with the distribution of natural or reusable material. The only clearance cairns found 

during the survey were particularly large and near the improved fields in the south-western corner 

of the study area, on the edge of Pontsticill reservoir. These clearance cairns probably date to 

between the post-medieval period to modern day and may have been created mechanically. The 

CPAT HER had many of these clearance cairns attributed to prehistoric activity in the area of 

Waun Rydd valley. 

Shooting butts 

5.11 Shooting butts were most commonly found on the eastern side of <strong>Mynydd</strong> <strong>Llangynidr</strong>, as 

there is copious amounts of outcropping rock out of which to construct the butts. These varied in 

form between simple hollows in the scree slopes, single curved walls and complete circles. They 

face all directions, but usually with a good view of the heath. 

The correlation of air photo transcriptions to sites 

5.12 Elements that correlated well were quarries, some structures and most of the field 

boundaries, some of these also correlating with field boundaries noted on 1st edition OS mapping. 

The record was augmented by construction details and identification of further structural units. 

More ephemeral features like possible cultivation or larger enclosures proved difficult to confirm 

on the ground.

6 Narrative summary and upland research themes 

Prehistoric 

6.1 The earliest archaeological evidence in the survey area is attributed to the Bronze Age. There 

were no sites recorded on the HER or found during the survey that related to the Mesolithic or the 

Neolithic period. 

6.2 The picture becomes a little clearer for the Bronze Age. There are 97 records for this period, 

with possibly a further seventeen. These sites include barrows, cairns, hut circles, enclosures and 

field boundaries. This is in contrast to the Iron Age, to which only six are attributed. 

Upland prehistoric settlement from the Mesolithic period onwards, only visible through 

artefact scatters around upland lakes 

6.3 No upland lakes were found in the survey area, but there are three post-medieval or modern 

reservoirs. No artefact scatters were recorded during the survey. 

The identification of upland settlement remains from periods where they are poorly 

represented, particularly the Bronze Age and Early Medieval periods 

6.4 There is good potential for prehistoric settlement within the area covered by this survey 

project as generally speaking the topography is not rugged and there is plenty of outcropping 

rock with which to build structures without the need to quarry into the bedrock. There were very 

few slopes in the area which were too steep or hazardous to negate settlement. Possible hut 

circles and a circular enclosure were found on the southern slope of Waun Rydd valley, and 

prehistoric cairns were found on both. Some of the sites seem to have been reused in the postmedieval 

period to create sheepfolds and further enclosures, something that is prevalent in these 

hills. 

Prehistoric ritual landscapes and their relationships with contemporary settlement 

6.5 The survey recorded a great number of cairns, but in many cases it was not possible to 

determine their date for certain. The definite prehistoric cairns were found throughout the survey 

area, including the summits of <strong>Mynydd</strong> <strong>Llangynidr</strong>, Carn Caws and Clo Cadno and on the top of 

Cefn yr Ystrad. Generally it does not seem that there is a particular correlation between the siting 

of these cairns and the contemporary settlements. Cairns were generally on the summits of the 

mountains, with a good view of the cairns on the uplands surrounding the site. Settlements were 

located mostly in the sheltered valley areas with a good supply of water and more fertile land. An 

exception could be the cairn at SO 12986 10787, which is located just north of a widespread 

prehistoric settlement on the Waun Rydd valley. It has a number of small cairns on its west side 

overlooking the Pontsticill reservoir and on its east side close to a well worn trackway orientated 

northeast - southwest down the valley. The settlement appears to include several phases of 

occupation, and it is not certain that the cairn is prehistoric. 

6.6 The impression overall is that prehistoric settlement must have been widespread but 

lightweight as there are few significant traces of field systems or settlement. It is possible that 

the medieval and post medieval farmsteads occupied the same sites for purely geographical 

reasons in which case only geophysical survey or excavation could recover traces of prehistoric 

predecessors. 

Medieval 

6.7 There are thirty records for the medieval period. This is perhaps somewhat lower than it 

should be, as it is frequently difficult to date sheepfolds, quarries and banks and it seems more 

conservative to offer a post-medieval or unknown date. The sites that have been recorded as 

medieval include platforms, settlements and field boundaries. 

Page 14 







Upland deserted settlements, particularly those of potential medieval date with cognisance of 

surrounding agricultural or storage features associated with the domestic buildings 

6.8 A few upland deserted settlements or farmsteads were recorded during the project, for 

instance the ruins located in the valley below <strong>Mynydd</strong> <strong>Llangynidr</strong>. Often air photo evidence is the 

first indicator of potential remains and usually identifies elements of the associated field system. 

Otherwise, these sites are discovered during systematic field visits to sheepfolds, where attention 

needs to be paid to incorporated remains of earlier structures. 

The structure, components and phasing of field systems in upland areas with an eye to 

possible early dating of some enclosures, and the presence of encroachment 

6.9 There were many former boundary walls discovered which had collapsed into banks. They 

were located on the north facing slopes of <strong>Mynydd</strong> <strong>Llangynidr</strong> and along the top of Carn Caws 

and Clo Cadno but were often very heavily obscured by vegetation or weather conditions. They 

are probably medieval or post-medieval. Early mapping can assist with dating post-medieval field 

systems but has been found to be of little use for earlier features. Associating field systems with 

date-specific structures and transport routes may be the only practical method of dating them. 

Post medieval 

6.10 There are 316 (plus a possible further twelve) records for the post medieval period, 

comprising almost half the records for the project. The period witnessed a dramatic increase in 

activity in the mountains as people of new skills and tools found gainful employment on the 

slopes. There were still the shepherds with their huts, folds and dips, but the industrial revolution 

signalled an improvement in quarrying techniques. Recreational shooting of course became 

widespread in upland areas during the 1800s. 

6.11 Most of the recorded sites were quarries and lime kilns, associated with spoil heaps and 

some buildings. The majority of the limekilns were surface kilns, heavily overgrown with waste 

heaps of burnt lime and charcoal material. There were some examples of well built stone pot 

kilns, some freestanding mounds, others dug into steep slopes. The loose waste material also 

inadvertently provided a material for walkers to construct recreational cairns out of. 

6.12 The shooting butts varied in form between single rubble walls, to crescent shaped circles, 

sometimes built out of older cairns. 

6.13 Very frequently observed sites in the survey area were hollows constructed in the scree 

slopes. It was clear that while most were roughly built holes probably associated with modern 

military training, some were of far better construction and had far superior views of the open 

mountainside. The latter were recorded as post medieval shooting butts, though of course, even 

some of the freestanding butts could be modern in date. 

The presence and extent of remains of rural industries in the uplands, particularly peat 

cutting, quarrying, rabbit farming and mining 

6.14 Quarrying for limestone to produce lime is the main industry present in the survey area and 

was found throughout, though the extent of each quarry varied widely. Other quarries were found 

to extract walling stone or other building materials in the later periods. There were a number of 

modern disused quarries in the area surveyed, with partially tarmaced roads and access routes 

that had been recently blocked off. Evidence of extensive quarrying was found along outcrops, 

such as above the area of forestry between SO 14300, 16400 and 14800, 16900, with frequent 

scalloping of the hillside. The topography sometimes made it difficult to distinguish between 

natural scree and specific areas of industrial quarrying. There were numerous small scoops in the 

slopes of most of the peaks and close to stone wall boundaries such as at SO 16468 13732 where 

stone for the wall was quarried on-site. 

Page 15 







6.15 Although a large percentage of the area surveyed was covered in peat of variable 

thickness, no examples of peat-cutting activity were visible but deep peat was not particularly 

common and didn’t exceed 1 metre deep in some places. 

The form and distribution of extraction landscapes and the association of defined mining 

areas and their mining features 

6.16 There was no mining recorded in the area, but the style of quarrying varied greatly. Often 

small individual scoops were recorded, particularly on the slopes west of Pen Cerrig-calch. It is 

difficult to date these scoops, but they are likely to have been excavated for an extensive lime 

producing industry in the post-medieval period. Occasionally they are located alongside boundary 

walls and it is clear that their function was to provide walling material. 

6.17 There are several major centres of stone extraction in the survey area dating to the modern 

period, which have recently become disused. These may have had post-medieval origins, 

including the ridge of Blaen Onneu, with a number of limekilns and smaller quarries in the vicinity. 

On the western side of Merthyr Common below Cefn yr Ystrad, there is reference in the CPAT 

HER 22147 to the ‘Baltic’ quarry which had signs of being extended and mechanised at a later 

date. These quarries are large scale and include quarry buildings and waste heaps clearly part of 

an organised industry and their locations on the outer edges of the Upland area suggests that 

they were positioned for ease of access and transport along major tracks. Higher up the slopes, in 

the more remote locations areas of small scale scoops into the natural stone outcrop might have 

earlier origins. They are somewhat disorganised when compared to the clearly post-medieval 

quarries and they could, for example, be medieval. 

Modern 

6.18 There were 49 modern sites recorded, mainly associated with recreational walkers’ cairns. 

Modern shelters in the form of hollows in the scree slopes were often not recorded, due to their 

abundance and frequently in dense clusters. Besides this there were multiple extensive quarries 

on the eastern and western extremities of the survey area which had recently become disused. 

There were also shelters and recreational cairns and a commemorative marker stone associated 

with a Welsh Water filter house. 

6.19 There are two air crash sites within the area, one, of Wellington bomber T2520 exists at SO 

09050 13750 where it crashed on the 9 th December, 1940. The other, of a Vampire jet VV618 

exists at SO 09450 09650 where it crashed on the 27 th October 1953. 

Page 16 







Other uplands research themes 

Agri-Industrial settlement patterns in contexts where farming and industrial activity coalesce 

6.20 Similarities in construction of some hearths and ovens inside domestic shepherds’ huts 

were shared with some of the lime kilns. Some limekilns were also very close to domestic 

settlement activity. This may suggest that small agricultural communities were involved in the 

lime producing industry further up the slopes and that they may have produced some lime for use 

within their own community. 

The relationship of sites to woodland, where it exists and to identified deposits of peat and 

areas of peat extraction or drainage 

6.21 The only areas of woodland in the survey area were on the boundaries of the area. 

6.22 The area of woodland was not associated with peat extraction in the area. Peat is 

widespread on the top of the survey area, but no examples of peat cutting were found during the 

survey. 

Transport networks of all periods in relation to the upland areas and the inter-regional 

implications of these, in particular extensive remains of upland trackways and early systems of 

roads and tramways with their associated infrastructure 

6.23 Most of the tracks in the survey area are difficult to date and were often still in use until 

recently to access quarries or by modern walkers. However, due to the wear on some of the 

tracks and the existence of a number of possible prehistoric cairns along the route, it is likely that 

some of the tracks have been used over a long period of time and may date back as far as the 

prehistoric period. Some of the quarry tracks could date to the medieval or post-medieval period, 

but have been updated and maintained for more recent use. 

6.24 Some tracks were probably established for accessing shooting butts, as these are a 

common feature particularly on the eastern side of the area where there is copious outcropping 

rock and easy access to the relatively flat areas. These might account for some of the more 

ephemeral track. 

6.25 The tracks and paths that run along the top of both ridges are likely to have been in use 

since antiquity. Prehistoric cairns and mounds are located on the ridges and peaks, but the paths 

are also denoted by marker cairns (which are probably of various dates). No boundary stones 

marking track were located during the survey, with the abundance of loose limestone scree 

probably making small cairns an easier way to mark the tracks. 

Page 17 







7 Appendix 1 

Environmental potential 

7.1 The extent of pollen sampling already carried within the area is unknown at the time of the 

survey. Pollen sampling could be worthwhile in the southern area of the site, particularly at SO 

14500, 13750 and SO 08500 11500, where extensive peat bogs exist, up to at least 1m in depth. 

Very little settlement activity was found in these areas. Beneath the peat in this area there is the 

possibility of relict soils. A specialist would be needed to target further sampling most effectively. 

Recommendations 

Documentary resource & NMRW 

7.2 Explore improved areas with geophysics to see what the potential would be to locate 

ploughed-down monuments in these areas. 

7.3 If the AP resource for these upland areas could be shared as geo-referenced images then 

their inclusion in a GIS would be straightforward. The information contained (vegetation and 

other surface details, not just archaeology) would benefit field survey. 

Further study 

7.4 There is potential for a combination of aerial photography and geophysical survey on 

improved ground to inform upon the apparent loss of monuments. Traces of monuments invisible 

to the eye at ground level may be visible from the air in certain conditions and geophysical survey 

could reveal aspects that were never visible. It is generally supposed that sites, such as 

prehistoric settlements, are potentially lost as ground is improved but the extent to which this 

occurs is not known.
