What makes this particular site quietly puzzling is a depression on its southern side, roughly eight metres across and just over half a metre deep, that does not quite fit the expected shape of the enclosure itself. It may be the sunken remains of a hut site, or it may indicate a souterrain, an underground stone-lined passage or chamber that early Irish communities used for storage and, in times of threat, for concealment.

The site was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a detailed regional study that catalogued the extraordinary concentration of monuments in this part of west Kerry. Low mounds sit on either side of the main earthwork, and the whole complex lies approximately 125 metres east of a related site. The landscape here carries layers of occupation that extend back well before written record, and the ambiguity of that southern depression is itself characteristic of the peninsula, where centuries of agricultural activity, erosion, and quiet ruin have blurred the edges of what was once deliberate and functional.
