Summary

This small fortification occupies a precipitous rock outcrop that forms a tidal island off the SW shore of Groatay, which itself lies immediately of the NE coast of North Uist. The defences comprise a single thick wall about 4m thick, which in places still stands 1m high. The wall peters out along the NE and SW flanks of the stack and there is no trace of it on the SE. The interior measures about 50m from NW to SE by 25m transversely (0.13ha) and appears to have been re-occupied in the Medieval or post-medieval period, with the construction of a substantial rectangular building at its SE end and three other oval structures elsewhere; the 1st edition OS 6-inch map shows three roofless rectangular structures within the interior (Inverness-shire, Hebrides, 1881, sheet 32). Erskine Beveridge noted a possible entrance at the NW end.
