It is all that remains of a house site of indeterminate age, and even that modest remnant is incomplete. The stones that once formed the walls were taken at some point and used to wall in the headland itself, a quiet act of recycling that has left the structure half-erased.

The house site sits in the south-western sector of a promontory enclosure known locally as Lisheen, from the Irish An Lisín, meaning the little ringfort. A ringfort, in its usual form, is a circular or oval enclosure defined by an earthen bank and ditch used as a farmstead or defended settlement, most commonly in early medieval Ireland. Here, though, the natural landscape does much of the defensive work. The enclosure consists of a stone wall built against a natural rock-scarp, running some 34 metres in length and rising to two metres both above the interior and above the fosse, the external ditch. Unusually, both the bank and the fosse curve outward toward the landward side, and the site is cut through by a natural arch in the rock. Writing in 1909, the antiquarian Thomas Johnson Westropp noted the reuse of the house-site stones for the headland wall, a detail that suggests the structure had already fallen out of use by the time anyone thought to record it carefully. The date of the house itself remains unknown.
