Occupying a knoll that forms the NE end of a small island that has been incorporated into the breakwater of Craobh Haven Marina, in 1983 the N and W flanks of this fort were destroyed during the construction of a causeway linking the island to the mainland. Roughly pear-shaped on plan beforehand, it measured 53m in length and tapered from 28m in breadth at the E end to some 13m at the W end (0.1ha) within a wall up to 4.5m thick. In the event, the wall survives only on the E and S, and the best preserved sectors of the outer face, which stood 1.1m high in six courses on the NNE, were removed; other short runs are visible around the E end, and there is a lump of vitrified stone in the wall on the S, where the wall takes in a shoulder of the knoll to form a re-entrant which is also the most likely position for the entrance. Apart from a small stone-founded hut thought by RCAHMS investigators to have been of relatively recent date, but now destroyed, the interior is featureless. Salvage excavations, however revealed evidence of occupation within the interior, and two radiocarbon sampes from beneath the wall returned dates in the second half of the 1st millennium BC (Nieke and Boyd 1987).
