Summary

This coastal promontory is located on the W side of Sherkin Island, off the SW coast of Co. Cork. Depicted as 'Carrigdoona' (rock of the fort) on the second edition OS six-inch map, it barely projects into the sea to the SW and its surface is only at about 3m OD. It is bounded by a tumble of large rocks to the SE and NE and elsewhere by the sea. Many of these stones are up to 1.8m in length, with those to the SE following the line of a shallow gully. The interior of the stack is flat, mainly consisting of bare rock, and is overlooked by a ridge to the S. There are no recorded features such as hut sites on the headland. A wedge tomb is located immediately outside the tumble of stones to the E of the promontory.
