Summary

Possible small contour hillfort or round located at end of prominent SE-facing spur above streams on E flowing into St Austell Bay on S. Steep slopes, moderate along ridge on NW. Roughly circular enclosing c. 0.81ha. Defined by three closely-spaced concentric ramparts and ditches, with incomplete fourth or more likely counterscarp on W. Ramparts range 1.3m to 2.7m, high inner best, outermost as partial scarp to 1.3m high. Possible staggered entrance on W, but no obvious break in third rampart, that on E possibly later. On N and E circuit overlain by field boundaries. Circular depression, 0.5m deep, outside fourth rampart on E side possible round house or small quarry. Chance finds of numerous flints, slingstones, stone axe and sherd of South-West Decorated pottery from interior. Pasture interior, wooded banks and Warren Wood to E and S. On 1st Ed. OS map (1882).
