The motte has a base diameter of 34m, is 6m high and has a flat summit 16m in diameter. The bailey lies to the E of the motte and measures 50m by 30m. It is separated from the motte by a the filled-in remains of a ditch, and is bounded by natural slopes to the N and S. An original causewayed entrance crosses the moat on the S side.
