A promontory fort defined by a single bank and outer ditch, and natural slopes on the N, NE and S, now forms the garden of a large house, Twyn Bell. The curving bank and ditch system measures about 24m across, the bank is 4m high above the house platform level, and extends for about 30m though its N and S ends have probably been levelled during landscaping. The ditch is 2m deep.
