What makes them linger in the mind is not their scale but a detail inside the oval enclosure: three shallow, stone-lined depressions arranged in a neat line across the interior floor, each roughly 1.2 metres across. No one has established what they were for.

The site lies about 100 metres south-west of Cahersavane caher, a caher being a stone-walled ringfort of the kind found across the Iveragh Peninsula, which itself forms the southern finger of land that reaches out into the Atlantic between Dingle Bay and the Kenmare River. The two structures here occupy the eastern end of a levelled area, with rough stone revetment, essentially a retaining face of stacked stone, shoring up the western and northern edges to keep the platform stable on the slope. The first structure is a crudely built circular foundation, possibly the remains of a small hut, about 7.7 metres in diameter and still standing to roughly a metre in height. The second is the oval enclosure, slightly smaller at around 10.4 by 6.7 metres, with walls now collapsed to about 0.6 metres. It is this second structure that holds the puzzle: those three lined depressions, evenly spaced, suggest something deliberate, perhaps storage pits, post settings, or something connected with an activity specific to this hilltop location, but the archaeology offers no firm answer. A. O'Sullivan and J. Sheehan, who surveyed the Iveragh Peninsula in research published by Cork University Press in 1996, recorded the depressions without resolving their purpose, and that uncertainty has remained.
