Summary

Univallate, partial contour hillfort, large for the area, sited on part of the summit of NW-SE ridge at the confluence of a stream with the Afon Cynin. Very steep cwm, with stream issues, on NE side. Steep or very steep surrounding slopes to N and E, moderate to strong on S and W and moderate along ridge to NW. Gently sloping interior from E-W. Polygonal in shape, measuring c. 95m across, with internal area 0.8ha. Bank and ditch surround, the former to 1.7m above the latter, with counterscarp to 0.5m high on N, though much reduced on E and S. Entrance on W. A triangular ledge juts out from the bank on N side of the entrance and a 60m long second bank or outwork, with entrance through its centre, provides additional protection. Affected by field banks on E and S sides. Under improved pasture. On 1st Ed. OS map (1889). Minimal investigations, undated.
