Isolated oval contour fort located on summit of a small hill above and near the mouth of the Afon Afan and the sea. Steep surrounding slopes. Measures 65m E-W by 30m wide enclosing 0.2ha. Defined by bank which follows the contours, only 0.3m internally but to nearly 3m external. Simple entrance at E end. Outside bank is berm c. 6m-10m wide followed by a second rampart which has gone on NE and at E of N side. Along W half of N side it shows as bank 3m wide and to 0.6m high and is best on W where to 6m wide and nearly 1m high. Along S forms a scarp fading into the natural slope. No ditches visible. Possibly buried features. Entrance through outer rampart again on E where shows gap 14m wide and traces of approach track winding down the hill. Traces of stone about the banks suggesting earth and rubble construction, but no obvious structural remains. Lower down the hill traces of possible third bank, showing as a scarp rather like the other two. Best seen on SE and on NE it follows a field boundary and on the NW affected by quarry). However, this may be a later field boundary. Heavy bracken cover to site and surrounding slopes. On 1st Ed. OS map (1877-78). Minimal investigations, undated.
