A cashel is a type of early Irish stone-walled enclosure, roughly equivalent to a ringfort but built from dry-laid stone rather than earthen banks, and this one, known as Lios Na Caolbhuí, has the quiet, half-legible quality of a settlement that time has pressed almost flat rather than demolished outright.

The best-preserved of the three huts sits against the enclosure wall at the northwest. Its internal diameter measures 5.9 metres, and though the wall survives to only around 0.6 metres in height, it is nearly 1.75 metres wide, suggesting a structure that was once considerably more substantial. The entrance, a gap of 1.2 metres in the inner face of the wall, faces south-south-east. The outer face of the wall is entirely obscured by collapse, so the original external profile can only be guessed at. Stranger still is a sub-rectangular space between this hut and the enclosing bank to the west, where drystone masonry up to 0.5 metres high has been laid against the north and east sides. What this space was used for is not known. The detail is recorded without explanation in J. Cuppage's 1986 archaeological survey of the Dingle Peninsula, and it remains unresolved. The site also contains a souterrain, an underground stone-lined passage that in early medieval contexts typically served for storage or, in times of threat, as a place of concealment.

The remains sit on fairly level ground with views eastward across Brandon Bay, which gives some sense of why this location was chosen: sheltered from the mountain behind, open to the coast ahead. The three huts together suggest a small community rather than a single household, though the archaeological record here is thin enough that speculation about who lived at Lios Na Caolbhuí, and when, would outrun the evidence.
