This small fortification occupies a coastal promontory, which is cut off on the SW by no less than three walls, the inner of which displays an exposure of vitrifaction. The cliff girt interior to the rear of this wall measures about 35m from NE to SW by a maximum of 17m transversely, the wall itself, however has been reduced to no more than a mound of rubble up to 1.6m high. The middle wall is no more than a short length 2m thick, the faces reduced to their basal courses but with the core standing 1m high, while the outer is about 2.5m thick by 1.2m high, with the lines of its faces preserved almost complete. The latter spans the whole neck of the promontory and is broken by an entrance towards its NW end. The interior is featureless. The different states of preservation of the three walls suggests that they may not all be contemporary.

First depicted on the 1st edition OS 25-inch map (Argyll and Bute 1881, sheet 221.1), it was visited in 1934 by Gordon Childe (Childe 1935, 81) and subsequently by the Islay Survey Group (Celoria 1959, N.7/9; Lamont 1959). In 1976 RCAHMS surveyed the fort for the County Inventory of Argyll (RCAHMS 1984, 93-4, no.156) and in 1979 it was visited by the OS. It was photographed from the air by RCAHMS in 1979, and Scheduled in 1993.
