What makes it worth pausing over is not its scale but a single structure at its north-eastern corner: a circular building constructed using corbelling, a technique in which courses of drystone are laid so that each projects slightly inward over the one below, eventually meeting at the top without the need for mortar or timber. Two recesses survive in the interior wall, one of which may originally have functioned as a window.

Judith Cuppage, writing in 1986 as part of a survey of the Corca Dhuibhne region, recorded the site and noted that other structures had been built up against the outer wall of the enclosure, suggesting they served as sheep-shelters or folds at some point in their use. The triangular enclosure itself, unusually large and now reduced to little more than a trace in the ground, would have enclosed and defined this activity. Whether the corbelled structure predates the pastoral use of the surrounding enclosure, or was always part of the same complex, is not resolved by what remains. On mountain terrain like this, where building materials had to be gathered locally and weather demanded compact, low construction, corbelling was a practical as much as a traditional choice, and the technique appears at sites across the Dingle Peninsula spanning many centuries.
