Summary

This fortification occupies a promontory on the NW coast of the Tangaval peninsular, which forms the SW extremity of Barra. The promontory is girt with cliffs up to 12m high, dropping sheer into the sea on the SW, while the outcrops on the seaward side of hollow cutting from E to W across its neck provide a natural line line of defence which has been exploited by a single wall. In places the wall stands 1m high and a gap at its E end is probably the entrance. The rocky interior is rough and uneven, and measures about 120m from NW to SE by a maximum of 65m transversely (0.5ha), though about a third of this area at the seaward end is exposed bedrock. The only feature visible within the interior is the tumbled ruin of a broch occupying the summit; measuring about 18m in diameter over a wall 4m in thickness and up to 1.2m in height, it has a possible entrance on the E.

Dating Evidence

The pottery found here and its comparisons to the broch on Dun Cuier (Young 1956, 293), may have no bearing on the dating of the outer defence.
