Summary

A tiny promontory connected to the foot of the steep coastal escarpment S of Seanchaisteal (Atlas No.2781) by a razor-backed neck, is partly enclosed by a bank. Little more than an outcrop dipping down to the sea on the E, the bank extends along its upper lip, facing onto the coastal escarpment overlooking it from the W, The entrance is at the S end where the neck joins it from the W. Dipping steeply down to the sea on either side, the crest of the promontory measures no more than 30m in length from N to S by 10m in breadth and is occupied by two contiguous rows of terraced structures, most of them measuring about 3m square internally, and one about 6m by 3m. The promontory is thought to be an early monastic site.
