High, rocky and somewhat mutilated, contour hillfort, one of a cluster of sites around the Llyn Clywedog reservoir (formerly the valley of the Afon Clywedog), and opposite to Fan Hill, Llanidloes. Surrounding slopes precipitous to N, very steep to S, steep to E, moderate to strong to W. Oval in plan, measuring 120m NNW-SSE by 70m across, with internal area 0.6ha. Bank and ditch still visible on E where main facade faces W. Double bank and medial ditch around part of NW, but reducing to single scarp on S. Counterscarp and quarry scoops on the N. Further bank and ditch outwork with possible stone revetment 30m downslope from entrance on NW, cut by entranceway and aligned with enclosure. Surviving ramparts suggest earthen banks, but stone revetments should not be discounted. Elaborate and interesting NW entrance with inturned and out-turned banks to inner banks and inturned to outer. Higher banks here. Rough upland grazing and bracken. On 1st Ed. OS map (1886). Minimal investigations, undated.
