Summary

The triangular tip of this precipitous coastal promontory is cut off on the SSW by twin ditches with a medial rampart. The W end of the flat-topped rampart stands 2m and 1.2m respectively above the bottoms of outer and inner ditches, which themselves measure 11m and 8m in breadth; there is an entrance midway along the rampart. The ground behind these defences rises into a low knoll, the summit of which measures about 12m across and is enclosed by a stony bank up to 1.4m high where it is best preserved on the N. To the W and N, the knoll descends into a confused mass of boulders and outcrops, though there is also a grassy terrace extending along the W cliff-edge to the very tip of the promontory. Leaving aside the enclosure on the summit, which is presumably the remains of a dun, the interior measures about 75m from NNE to SSW by a maximum of 44m transversely (0.18ha) immediately behind the defences, falling away sheer to the sea along the W margin, and descending steeply through broken outcrops on the E.
