Blaencar Enclosure NGR :- SO045141 (SO01SW) Unitary authority :- Powys Community :- Talybont-on-usk Preferred site type :- Medieval ? - Hafod ? (Earthwork - Near intact ) REMAINS OF 2 PARELLEL DITCHES WITH MEDIAL BANK FORMING A TRAPEZOIDAL ENCLOSURE (SIDES 135M 106M 121M AND 106M) DERELICT BUILDING SOME 6M BY 5M BY 3.5M HIGH IN SE QUADRANT. POSSIBLY A HAFOD. (Information from CPAT SMR, 2004). The Enclosure is known from the 1890 OS as Ty'r Yr Adar (Gamekeepers house). It is comprised of a trapezoidal shaped enclosure of area 1.5 hectares. The banks of the enclosure occasionally terminate for 1 m, and then continue, possibly due to natural erosion or worn down paths. Shallow ditches on either side flank the banks; the ditch-bank-ditch earthwork is 1.5 m in width. The enclosure has been poorly mapped by OS, banks have gradually disappeared on maps. The mapped extent of the enclosure matches that first suggested by the 1890 OS, however some of the banks are hard to discern amongst the marshy ground. The enclosure is dissected on its western side into two halves by a bank. The enclosure is of length 128-148 m, and width 112-119 m. The remains of 5 oak posts were found on the banks, some were upstanding and some had fallen over. These may have formed a fence line protecting the eastern side of the enclosure. The structure within the enclosure has been mostly destroyed via tree root action. Two trees grow within the structure which also contains a number of large feed barrels - the structure is disused. A large amount of tumbled stone (155 sq m) surrounds the standing walls of the structure. The structure is 6.5 m in length, 5.5 m in width. One piece of some roof slate was found on the site, no other slates were seen. The structure survives to a height of 3 m. James Bonsall, Earthsound Archaeological Geophysics, 18/APRIL/2004.
