What makes this site quietly remarkable is not any single structure but the combination: five rectangular huts, a network of field walls, and a souterrain, all partly submerged in boggy pasture, preserving in compressed form the outline of what was once an organised settlement.

The souterrain itself, a type of dry-built underground passage used in early medieval Ireland, often for storage or refuge, takes an unusual L-shaped plan here. Two passages meet at right angles, connected by a double lintelled creepway, meaning a low, roofed crawl-through formed from horizontal stone slabs set in pairs. The east-west passage runs 2.7 metres long and just under a metre high, wide enough for a person to move through with some care; the north-south passage is slightly shorter at 2 metres and narrower still at 0.8 metres. The whole thing is drystone construction, built without mortar, relying entirely on the careful placement of stone to hold its shape. That it survives at all beneath the encroaching bog is a small accident of topography, the slight rise on which it sits having kept it just clear of full submersion.

The wider complex of huts and field walls gives the site an additional layer of interest, suggesting a community organised enough to manage land division and permanent structures, though the bog has since reclaimed much of what they built. The site sits within the Iveragh Peninsula, and its surroundings, a horseshoe of hills cupping a waterlogged valley floor, give some sense of how remote and self-contained such a settlement would have been.
