The site reportedly contained a souterrain, an underground stone-lined passage or chamber of the kind typically associated with early medieval settlement in Ireland, used for storage, refuge, or both. Whether the underground element survives in any meaningful form is uncertain; the surface remains are described as very ruined, and the cashel, a dry-stone walled enclosure of the type common across early Christian Ireland, is difficult to read against the landscape.

The remains sit on ground that overlooks Smerwick Harbour and the flat plain drained by the Feohanagh river, with Ballydavid Head rising behind. Within the enclosure, traces of three hut-sites are visible, suggesting a small farming or pastoral settlement of the early medieval period. The site was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a detailed field study of one of the most archaeologically dense landscapes in Ireland. The persistence of the local name 'lios' into modern times is itself notable; such oral traditions frequently preserve the memory of a site long after its physical features have become unreadable to the casual eye.
