Summary

This coastal promontory is situated S of 'Kid Island' at Dunanierin, W of 'Rinroe Point', Co. Mayo. Projecting SW into Broad Haven, the headland is known as 'Dunanierin' from a popular 'legend derived from Iarnain (Ferreolus) Barratt, who built a castle of lime and stone there' (Westropp 1912, 127). It is connected to the mainland on the NE by a narrow neck, where Westropp noted in 1912 that the remains were insignificant, and 'after the great rains of August, 1910, much of the earth-cap of the narrow isthmus has slipped down with some of the headland itself' (ibid., 128). The gatehouse of a medieval fortification remain along with a possible rectangular building on the summit. The remains of the earlier fort comprise a bank and ditch drawn in a shallow arc across the landward approach to the neck. Westropp notes that the bank had been pushed into the ditch, which is 0.6m deep and 1.8m wide. The bank was in a bad state of repair but in places it was 0.9m high. There are no traces of earlier remains within the interior, which has suffered severe coastal erosion.

Enclosing Works

The remains of the earlier fort lie on the landward side of the neck and are composed of a bank and ditch drawn across the NE approach in a shallow arc. Westropp notes that the bank had been pushed into the ditch, which is 0.6m deep and 1.8m wide. The bank was in a bad state of repair but in places it was 0.9m high.
