Possible inland promontory fort located at domed S end of promontory situated along river to Sandyhaven Pill. Steep sided surrounding slopes on E, S and W drop by 20m-30m to stream valleys with easily approachable N side. Medieval, and predominantly earthwork motte and bailey castle throughout its existence, thought to have occupied earlier fort. To N 150m long curving bank and ditch cuts off promontory, defending interior c. 185m N-S by c.70 with area c. 1.3ha. Simple N-facing gap to a small, sub-circular annexe, c. 60m E-W by 50m. According to Ordnance Survey annexe possibly underlies rampart. Midway across narrowest neck of promontory more 50m of a, more massive, second rampart, of uncertain Iron Age or medieval date, dividing site into outer bailey to N, divided into two by N-S scarp, and an inner bailey to S. Mound, c. 6m high and 23m wide, built against S side of inner rampart, with a weak ditch on two sides and a steep natural slope to E, possibly site of the motte. Interior under pasture and banks under wood, with wooded surrounds. On 1st Ed. OS map (1874-1975). Minimal investigations, undated.
