The curved, almost lunar form sets it apart; the majority of prehistoric stone cairns in Ireland tend toward round or oval profiles, used to mark burials or prominent ridgelines. This one, with its asymmetrical crescent shape, occupies quieter ground without obvious theatrical placement in the landscape.

The structure measures up to 15.2 metres at its longest, 7 metres across, and stands roughly 2.5 metres at its highest point, making it a substantial presence despite its low-lying position. It was recorded as part of the Corca Dhuibhne archaeological survey of the Dingle Peninsula, published in 1986 by J. Cuppage, a thorough regional survey that documented the remarkable density of prehistoric and early medieval monuments along this stretch of the Kerry coast. The Dingle Peninsula is one of the most archaeologically layered landscapes in Ireland, and a cairn of this size, however understated its setting, fits into a wider pattern of monument-building that spans several millennia in the area. Whether the crescent form is original or the result of later disturbance and stone robbing, which was common practice when field clearance or building material was needed, is not firmly established.
