Summary

Located on the S end of Clare Island off the W coast of Co. Mayo, this coastal promontory is marked as 'Doon' on the first edition OS six-inch map (1839). Projecting SW from the Island at Ooghaniska Cove, it is long and narrow, some 150m in length overall and rising to seaward on the SW. The grassy slope dipping into the low neck, which lies about 3m below the level of the old fields to the N, is c. 8.2m wide and, is traversed by two shallow ditches with rock outcrop between them. The outer ditch runs ENE and WSW and is 2.7m wide by 0.9m deep. The inner lies E and W c. 10m to seaward and is 2.7m wide by 0.9m deep. A wall 'rarely over 3 feet high and 6 feet thick' seems to have extended along the NW margin of the promontory above a path created by scarping the slope. Ranging from 1.2m to 2.7m thick, Westropp describes this wall with a 'bastion' at the entrance at the head of the path. The raised area enclosed measures about 60m long by up to 21m wide and contains two hut-sites. The northern has rounded corners and measures 6.4m N-S by 5.4m E-W, with earth and stone walls 1.2m thick. The second lies 4.5m to the S and has an irregular plan, measuring 6m N/S by 9m E/W; it has rounded corners with walls 1.2m thick. To the S the ground has been formed into three shallow terraces 0.6m high and 3.6m wide.

Landscape

Hillfort Type

Projecting SW from the Island at Ooghaniska Cove, this is a long narrow promontory 150m in length rising to seaward on the SW. Scarping along the NW face has created a terrace carrying a path. The raised seaward end measures 60m long and 21m wide. The low grassy dip at the neck is c. 3m below the old fields to the N and has a sloped approach c. 8.2m wide, fenced by two shallow ditches. A 'bastion' described by Westropp was fenced by a wall 1.2m thick adjoined by a similar wall 2.7m thick at the head of the path where the entrance was located.

Entrances

A 'bastion' described by Westropp was fenced by a wall 1.2m thick adjoined by a similar wall 2.7m thick at the head of the path where the entrance was located. Its precise position is not recorded, but the path was apparently on the NW flank.
