Uplands Initiative – <str<strong>on</strong>g>Banc</str<strong>on</strong>g> y <str<strong>on</strong>g>Celyn</str<strong>on</strong>g> 20083.2.3 Significance of <strong>the</strong> prehistoric archaeologyThe number of prehistoric m<strong>on</strong>uments and finds within <strong>the</strong> <str<strong>on</strong>g>Banc</str<strong>on</strong>g> y <str<strong>on</strong>g>Celyn</str<strong>on</strong>g> study area isnot high. There is no evidence of prehistoric settlement and <strong>the</strong> evidence from within<strong>the</strong> study area is limited to Neolithic and Br<strong>on</strong>ze Age funerary m<strong>on</strong>uments, as well as apossible Br<strong>on</strong>ze Age st<strong>on</strong>e circle <strong>on</strong> <str<strong>on</strong>g>Banc</str<strong>on</strong>g> y <str<strong>on</strong>g>Celyn</str<strong>on</strong>g> hill. Occasi<strong>on</strong>al finds of Neolithicand Br<strong>on</strong>ze Age artefacts outside <strong>the</strong> study area are, however, suggestive of settledcommunities exploiting <strong>the</strong> wider landscape during both periods.The presence of a small Neolithic chambered tomb at Bailey Bach is of c<strong>on</strong>siderablesignificance in view of <strong>the</strong> rarity of such m<strong>on</strong>uments in upland c<strong>on</strong>texts in mid-Wales.The major Neolithic chambered tombs of Brec<strong>on</strong>shire are located much fur<strong>the</strong>r to <strong>the</strong>east, and are c<strong>on</strong>siderably larger than <strong>the</strong> Bailey Bach example. Its diminutive sizemakes it unsurprising that Bailey Bach was originally described as a cist or a roundcairn, but it would appear to bear similar characteristics to some of <strong>the</strong> smaller, simplertombs or cromlechs seen in southwest Wales, such as <strong>the</strong> Carn Wnda burial chamber atLlanwnda, Pembrokeshire. The significance of this site is recognised by its protecti<strong>on</strong>as a Scheduled <strong>Ancient</strong> M<strong>on</strong>ument.The group of over 20 Br<strong>on</strong>ze Age cairns now recorded within <strong>the</strong> study area aresignificant as <strong>the</strong>y are evidence of a settled Br<strong>on</strong>ze Age populati<strong>on</strong> in <strong>the</strong> landscape, but<strong>the</strong> positi<strong>on</strong> of many of <strong>the</strong> large cairns al<strong>on</strong>g <strong>the</strong> high ground of Cefn Clawdd andTwyn y Post may also tell us that some may have been positi<strong>on</strong>ed to be visible from <strong>the</strong>east and nor<strong>the</strong>ast. The Cefn Clawdd Cairn NPRN 305784 is now <strong>the</strong> <strong>on</strong>ly <strong>on</strong>e of <strong>the</strong>group that is sufficiently well preserved to be seen <strong>on</strong> <strong>the</strong> skyline from that directi<strong>on</strong>.The cairns of Twyn y Post and Gwaun Ymrys<strong>on</strong> are now ra<strong>the</strong>r denuded, <strong>the</strong>refore it isdifficult to know how visible <strong>the</strong>y originally were in <strong>the</strong> landscape. However, it is veryinteresting to note that <strong>the</strong> old Brec<strong>on</strong> to Builth Wells road (NPRN 247185), which mayhave it origins as a medieval, or even a Roman road, follows a line of cairns northwardsfrom NPRN 247232 <strong>on</strong> Cefn Clawdd, past Twyn y Post Cairn II (NPRN 247191), <strong>the</strong>Prehistoric M<strong>on</strong>ument Complex at Twyn y Post (NPRN 307215), <strong>the</strong> Blaen Llwyn DduCairn (NPRN 305778) and also <strong>the</strong> Llyn Pen y Lan Cairn (NPRN 247192). It is notunreas<strong>on</strong>able to suspect that <strong>the</strong>se ancient cairns have been used to guide travellersacross <strong>the</strong> open moor for many centuries. It is also possible that much st<strong>on</strong>e was takenfrom <strong>the</strong>se cairns, over time, to help maintain or repair <strong>the</strong> road surface.Six of <strong>the</strong> <str<strong>on</strong>g>Banc</str<strong>on</strong>g> y <str<strong>on</strong>g>Celyn</str<strong>on</strong>g> Br<strong>on</strong>ze Age cairns are protected as Scheduled <strong>Ancient</strong>M<strong>on</strong>uments, including <strong>the</strong> three within <strong>the</strong> Twyn y Post Prehistoric M<strong>on</strong>umentComplex. Collectively, <strong>the</strong> funerary m<strong>on</strong>uments of <strong>the</strong> study area are of highsignificance as a group, despite <strong>the</strong> fact that most are now in poor c<strong>on</strong>diti<strong>on</strong> due to st<strong>on</strong>erobbing or erosi<strong>on</strong>.The <strong>on</strong>ly o<strong>the</strong>r prehistoric m<strong>on</strong>ument in <strong>the</strong> area is <strong>the</strong> <str<strong>on</strong>g>Banc</str<strong>on</strong>g> y <str<strong>on</strong>g>Celyn</str<strong>on</strong>g> St<strong>on</strong>e Circle. Itssignificance is questi<strong>on</strong>able, despite its status as a Scheduled <strong>Ancient</strong> M<strong>on</strong>ument, as itpresents little surface evidence of being a st<strong>on</strong>e circle. Without fur<strong>the</strong>r study, includingexcavati<strong>on</strong>, <strong>the</strong> archaeological significance of this site is difficult to determine, althoughCPAT have linked this site with several o<strong>the</strong>r small st<strong>on</strong>e circles as a new type of ritualm<strong>on</strong>ument in <strong>the</strong> Powys landscape (J<strong>on</strong>es, 2008, p.25-32).41
