(NR 7408 5480) Fort (NR)

OS 6" map, (1924)

This fort, occupying the summit of an isolated rocky knoll, measures 24.5m x 18.5m within a 6.1m thick wall, now reduced to a grass-covered stony bank, not more than 1.0m high. A number of facing stones are visible in situ as shown in plan. A subsidiary crest line, traceable all round the knoll except on the W, may represent the edge of a terrace made as a seating for the outer face of the wall. The exceptional wall thickness would allow for mural chambers and galleries but no trace of such structures are now visible. The entrance is in the E. A D-shaped enclosure, formed by a low bank, and measuring 27.5m x 9m internally is situated at the base of the knoll, immediately SE of the entrance. Without excavation it is impossible to assess its relationship to the fort.
