Summary

This promontory is located at the mouth of a linear chasm known as 'Ooghmore' on the S end of Inishturk Island off the W coast of Co. Mayo. A triangular portion of land on the E cliff of the chasm measuring 23m long and 11m across is cut off by a wall largely formed by a revetment along the rocky margin. Westropp notes that this is nearly straight and that the facing is composed of fine regular stone-work of several courses. The wall has been 2.4m thick, but the inner facing is smaller with set slabs 'veneering its face' (1914, 329). There are no recorded hut sites within the enclosed area and Westropp notes that most of the wall was removed 'not very long ago to fence the dangerous chasm' (ibid).

Enclosing Works

A wall formed a revetment to the rocky edge of the platform. Westropp notes that this is nearly straight barley showing a slight curve at one part. The facing is composed of fine regular stone-work of several courses and is 2.4m thick. The inner facing is smaller with set slabs 'veneering its face' (1914, 329).
