Summary

This coastal promontory is first noted as a fort by Raymond Lamb (1979, 20), though the western of two dashed circles shown here is annotated 'Graves' on the 1st edition OS 25-inch map (Orkney 1882, sheet 109.7) and it was also visited in 1964 by Keith Blood of the OS, who noted only two banks 0.5m high, which he believed were the remnants of a heavily-eroded building. Lamb gives no description of any defences as such, concentrating more on its spectacular natural scenery and the sea arches that have riven its flanks to create five legs supporting little more than a narrow spine. Nevertheless, he describes a series of circular and rectangular structures strung out beside the path along its crest, and there can be little doubt that these are the remains of either a promontory fort or a small monastic site. The surviving finger of land on its summit, however, measures no more than 35m in length by 6m in breadth (max 0.03 ha).
