Summary

Large, complex, bivallate, partial contour hillfort, with concentric annexe and additional small enclosure on S side, located on E-facing slope just off summit of rounded hill at the headwaters of Knock Brook, a tributary of the Western Cleddau. Moderate surrounding slopes to N, but steeper on E, S and W, especially on SE. The total site measures c. 270m across external, with internal area c. 5.25ha. An inner enclosure with two widely-spaced ramparts, possibly original enclosure of c. 58m internal diameter. SE half of this now missing, leaving a visible semi-circular area c. 58m by 45m, now undefended on the downslope SE side. However traces of the former ramparts here can be made out on aerial photographs. Inner bank is to 1.7m high with outside ditch, the outer being c. 15m distant, also to c. 1.7m high. To 60m - 100m from the inner banks rampart forms a concentric annexe, also discontinuous on SE. Earthworks of roughly oval enclosure, c. 63m N-S by 46m, lie to SE, and aerial photographs indicate that missing section of the annexe rampart survives as low earthwork curving in to NE around this oval enclosure. No entrances visible and possibly were located where sections missing. Under improved pasture now, but once ploughed. On 1st Ed. OS map (1889). Minimal investigations, undated.
