Summary

Pig Island is located E of Benwee Head, immediately N of the promontory fort at 'Doonmara' (MA004-001) on the N coast of Co. Mayo. It is can be described as a long, narrow island (c. 570M N/S by c. 50m E/W), situated c. 300m from the sheer cliffs of the mainland to the S. It is recorded in Archaeological Survey Database of the National Monuments Service as the site of a potential promontory fort, the co-ordinates falling on the N end of the island. The origin of this record is probably a linear feature visible on satellite imagery midway along the broader end of the island some 150m N of the S end, though it is not clear whether this is the remains of a boundary wall, or perhaps a geological feature visible in the exposed rock of the cliff on the W (SH).
