This coastal promontory, situated immediately W of Glash Island, projects NE from a long peninsula into Broad Haven Bay at an altitude of 6m OD, on the N coast of Co. Mayo. It is a finger of land no more than 15m wide and extending 60m NE from a narrow neck on the SW. First identified from aerial photographs by Casey (1999, 198), the Archaeological Survey Database of the National Monuments Service notes that fieldwork indicates there are no defences here.
