On the flat top of the knoll are remains of a roughly square enclosure, 5.5m N-S x 6.0 overall, consisting of turf-grown limestone rubble & block banks 1.0m high x 1.5m wide. There is a vague entrance gap in the middle of the E wall and along the exterior from this to the NE corner runs a shelf projecting 1.5m x 0.6m high.
