Summary

This small fortification comprises a stone wall some 15m in length cutting across the narrow neck of a precipitous promontory. Unusually, the neck also forms a summit, from which the ground falls away on both the landward and seaward sides, on the latter to a form a large hammer-headed end to the promontory. Spread about 3.3m in thickness, the wall is reduced to a stony scarp up to 1.3m in height along the leading edge of the summit on the landward side, below which a terrace has been cut back into the slope. This is broken midway across the neck by what appears to be an entrance lined with boulders on either side, and on the S side of the neck there are also traces of a second terrace lower down the slope. While the purpose of the outer of these terraces is uncertain, the inner of these terraces almost certainly forms part of the defences, though there is little sign of any structural stonework along its line. Immediately behind the wall, a marked hollow can be seen in the summit, giving the impression that these are the remains of a broch or dun that has collapsed over the cliff on the N, but in practice the lip of this hollow on the S and W is entirely natural. The rest of the promontory, which extends to about 0.2ha, is featureless, the seaward side descending into bare eroded rock.
