The hut foundation at Lisculliheen, known in Irish as Lios Coilichín, survives to a diameter of just 6.2 metres internally, its entrance facing the southeast. It is a quietly reduced thing, enough to suggest a life once arranged within it, but not enough to make that life easy to picture.

The hut sits inside a univallate rath, a type of early medieval enclosure defined by a single surrounding earthen bank. These raths, sometimes called ring forts, were the standard unit of rural settlement across Ireland for much of the first millennium and into the early medieval period, typically housing a farming family and their animals. This particular example occupies the northern side of an east-flowing stream, with a laneway running along its western edge. Within the enclosed interior, alongside the hut foundations, there is also a souterrain, an underground stone-lined passage or chamber that would have served for storage or, in times of threat, concealment. The combination of hut and souterrain within a single bank places this site firmly within a pattern repeated across the Dingle Peninsula, though each instance carries its own particular geography. The site was documented as part of the Corca Dhuibhne Archaeological Survey of the Dingle Peninsula, published in 1986.
