Two lines of encircling defence, outer circuit encloses oval area, c. 78m E-W by 66m, with area 0.5ha, inner circuit wall enclosing oval area, c. 50m E-W by 42m with area 0.21ha. Outer being a bank of earth with an external ditch, which reaches a maximum height of 3m+. Stone revetment of laid masonry can be traced on the NW outer face, and a slight counterscarp bank on S. E side merges into the natural slope. Inner circuit heavily robbed stone wall c. 4m-5m wide. Simple gap through both ramparts on the SE but badly damaged.
