Summary

This cliff-girt islet, with rises sheer out of the sound between Mingulay and Berneray (Barra Head), is defended by a wall built along the leading edge of a terrace halfway down the NE flank, overlooking the broad wave-cut platform that provides the only point of access from the sea. The wall is some 30m in length and towards its S end the rough outer face stands up to 1.5m in height. There is no entrance through the wall, and the only access to the summit of the island is via the outcrops climbing steadily round its N end. The top of the island is relatively level, measuring about 150m from ENE to WSW by 85m transversely (1ha). The footings of at least five structures are visible on it, the largest of which is a remarkable rectangular building measuring 7m from E to W by 3.3m transversely within a wall no more than 0.75m in thickness and probably comprising a bank with an internal face of slabs. The entrance is in the E end, flanked by two upright slabs up to 1m in height which seem to have supported a massive lintel; this now lies fallen across the passage-way, which was probably also protected from the prevailing wind by an external baffle wall. This is probably not a prehistoric fortification, but the wall is evidently designed to control access, and while it might be the vallum of a monastic site, it might equally be the defences of a medieval or post-medieval stronghold. The RCAHMS investigators did not visit the island in 1915, but they were told, probably by the boatman, that there was a church of stone and lime on it, presumably a reference to the large rectangular building (RCAHMS 1928, 137, no. 468), and perhaps hinting at a local tradition that this was monastic enclosure.

Investigations:
1st Identified Map Depiction (1878):   The large rectangular building is annotated Dun on the 1st edition OS 6-inch map (Inverness-shire, Hebrides 1880, sheet 70)
Other (1915):   Description based on observation from adjacent islands (RCAHMS 1928, 137, no. 468)
Other (1915):   Description by J Wedderspoon, but probably from observations from the adjacent islands and the sea
