Summary

The remains of a fort occupy a precipitous promontory on the NW side of a small sandy bay towards the W end of the indented N coast of Copinsay. Its defences comprise at least one wall set on the crest overlooking the neck on the SW, but there is also a drystone wall some 0.8m high cutting across the neck on the slope below it, though this is perhaps of more recent date. In 1970 the inner wall was exposed in the cliff-sections to either side and there were traces of a wall at the seaward tip of the promontory, where numerous slabs protruded through the turf. The interior measures about 26m from NE to SW by little more than 5m transversely (0.02ha), and while otherwise featureless, a cist-like structure was found here about 1925; a stone axe was also discovered (Mooney 1926).
