Summary

The summit of this rocky ridge is enclosed by a large fort measuring internally about 110m from N to S by 32m transversely (0.35ha). The inner defences comprise a single wall, which is principally visible at the N and S ends of the summit, though it can also be traced along the precipitous margins at the S end, but at the N end two additional outer walls can be seen cutting across the spine of the ridge on terraces lower down the slope. These latter are usually considered outworks, though the inner of them might easily have served as a freestanding defence in view of the character of the topography and as such would have substantially increased the size of the interior to 0.43ha. All the walls have been reduced to bands of rubble with only occasional facing stones visible. The only easy line of approach is from the N, following gullies and terraces on the E margin of the ridge up to a gap in the innermost wall on the NNE. The rocky interior is featureless.
