A small fortification occupies a low coastal knoll on the SW shore of the peninsular WNW of the Ardbeg distillery. Roughly oval on plan, it measures about 29m from NNE to SSW by 13m transversely within a wall largely reduced to a band of rubble with occasional outer facing-stones (0.03ha). To the NNE where the crest of the knoll descends in two terraces, another wall extends around the lip of the upper, while a third can be seen on the tip of the lower. No entrance is visible, though a narrow gully on the NW provides ready access, and the only feature visible within the interior is one angle of a rectangular building. Even including the terrace enclosed on the NNE, the interior of this enclosure is so small that, it is more akin to a dun than a small fort.
