Large, univallate, partial contour fort located on the broad E summit of a prominent E-W aligned ridge (Y Gaer, Llandewi Ystradenni - Atlas No. 1378 is on the W peak) overlooking the River Ithon. Site cuts across the contours to S. Surrounding slopes steep to N and S, moderate to E and W along the ridge. Measures c. 279m by 190m, with internal area 4.66ha. Defined by a single rampart and ditch, except on N, where two banks (the outer may well be a broad counterscarp, however) and medial ditch and where best preserved. On S defences only a scarp or flattened. Possible annexe c. 44m by 45m, to NE. Inturned entrances on E and W, more so on latter. Entrance on E damaged. Four later breaches. Two possible building platforms, but not proven. Predominantly pasture interior with some scrub and trees on banks. On 1st Ed. OS map (1889). Few investigations. Undated.
