Summary

This coastal promontory is annotated 'Doonmara' (the sea fort) on the first edition OS six-inch map (1839) and is situated S of 'Pig Island' c. 5.4km NE of Carrowteige Village, Co. Mayo. Projecting N from the mainland the promontory is composed of high rock outcrop, capped at the top of the cliff by bog. Westropp observed that he could only say that 'there seem to be fallen heaps of stone along the edges' but could say 'nothing as to its true character (1912, 121). There are no recorded structures. No trace of any defences is visible on the top of the promontory on satellite imagery, and its flanks form an inhospitable escarpment dropping into the sea (SH).
