A clochan (the singular form; clochans are the drystone, corbelled huts found across the Dingle Peninsula and beyond) is curious enough on its own, but a triple example, linked by lintelled passageways and concealing a souterrain opening directly from the floor of the central hut, is something else. A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement and used variously for storage, refuge, or ventilation. That one begins beneath your feet inside the largest hut adds a distinct quality to the place.

The central hut is the most substantial of the three, measuring 5.6 metres in diameter internally, with walls surviving to a height of 2.25 metres. A small niche is set into the wall at the northwest, carefully lintelled, and a possible drain, now blocked, opens off the southern inner face. More puzzling are the stones set on edge in the interior floor, protruding slightly above the gravel surface; their purpose has not been established. Low passages connect the central hut to an eastern chamber, roughly 4 metres across and also retaining its wall niches, and to a smaller western hut just 3 to 3.5 metres in diameter, its walls surviving to only 1.1 metres. A subsidiary rectangular chamber abuts the eastern hut from the southeast, but this may not be ancient; when the artist and antiquarian George Victor Du Noyer visited and recorded the site in 1858, he made no mention of it, nor of the paved pathway that now leads toward the entrance. Du Noyer did describe a flight of steps on the outside of the central hut's southern wall, a feature that has since entirely disappeared. By 1899, R. A. S. Macalister was noting traces of a blocked doorway in the eastern hut's southern wall, though no evidence of this is visible today either. The site has been quietly changing, losing some details and gaining others, across the span of recorded observation.
