Promontory forts, known in Irish as dúnta, are among the more dramatic features of the Irish coastline; they use a natural headland as their defence, with a bank or wall cut across the neck of land to enclose the interior. Inside this one, the faint traces of a circular dwelling survive, the kind of structure that would once have been home to people making use of the fort's protected space, whether as a permanent settlement or a seasonal refuge.

The hut site was recorded by T. J. Westropp in 1915, who noted its circular remains within the fort's interior. Westropp was a tireless documenter of Irish antiquities in the late nineteenth and early twentieth centuries, and his fieldwork across Munster in particular captured details of sites that have since become harder to read on the ground. His brief note from 1915 is the primary record of this feature, placing it within what was already an established archaeological monument at the time of his visit.
