Summary

Possible inland promontory fort located on slight SE-facing promontory above wooded re-entrant valley and stream to S at Llantood. Site of medieval motte and bailey castle, possibly within this is an earlier enclosure, but not proven. Steep valley sides to S quadrants. Polygonal interior measures c. 52m SE-NW by 50m, tapering to 30m on NW. Internal area not defined, but c. 0.3ha. Curving rampart cuts of promontory on N quadrants, standing to 7m above rock-cut ditch c. 5m-6m wide. No bank on W side and no main bank to S, although ditch and counterscarp in evidence. RCAHMW (Coflein) suggests defences possibly double on N. Motte to 4m high and 20m wide in S part of enclosure. No entrance defined. Rough grass interior, with gorse, bracken and bramble on banks and motte. Woodland surrounds to S. On 1st Ed. OS map (1889). Minimal investigations, undated.
