4In Raftery's (1972) classification of Irish hillforts, the 40 known examples were divided into three groups. Class 1 hillforts comprised single-walled sites. Class 2 sites were defined as widely-spaced, multi-walled defenses on hilltops and cliffs, such as DĂșn Aonghasa, Co. Galway, and Cahercommaun, Co. Kerry. Class 3 included inland promontory forts such as Caherconree.

The fort is is the third highest in Ireland and Britain, with Ben Graim Beg in Scotland the highest. Using metadata within our aerial photographs, we determined the elevation of the fort to be 615m (2,018 ft). Further to the west on the Dingle Peninsula is the Faha Promotory Fort, at 777m (2526 ft.) Faha may be seen in a 3D model by Dr. James O'Driscoll here.

Another Dingle Peninsula promontory fort, in this instance guarded on three sides by the ocean, is Dunbeg Fort.
