Summary

Contour hillfort located on isolated rounded hill N of Coychurch between the Ewenny and Ogmore rivers. Surrounding slopes moderate to E, stronger elsewhere. Measures c. 180m E-W by 170m with internal area 2.5ha. Badly degraded now, banks represented by just breaks of slope, best seen in N half, when in the RCAHMW investigation of 1963 it was 9m wide and c.0.8m high. To S line of field bank may be circuit outline. Traces of possibly an outer rampart or ramparts on N side, no ditches. No internal features. Pasture. Badly degraded by cultivation, probable position of banks now just breaks of slope. Minimal investigations, undated.
