Summary

Destroyed hillslope fort located in prominent position on SE-facing slope of NE-facing spur above the Afon Dewi Fawr to E, a tributary of the Afon Taf. Moderate to strong surrounding slopes on N and W, steep on E and S. Bulldozed and ploughed from 1985 and levelled 1983. Now effectively cropmark only, but bank just visible as a slight rise 15-20m wide and ditch as a slight hollow. Prior to destruction site was univallate and roughly circular in form of c. 85m diameter. Formerly single strong rampart of shattered stone and earth with ditch on the N and W sides, the bank to 4m high external, and weak bank on the SE overlooking the steep slope. Simple SW entrance. Under improved pasture with wood to E. On 1st Ed. Os map (1889). Minimal investigations, undated.
