Is it a souterrain, one of the underground stone-lined passages that early medieval communities used for storage or refuge, or is it something older and stranger: a subterranean hut, a circular chamber built to be lived in rather than simply used? That uncertainty is not a failure of the record but part of what makes the site genuinely interesting.

When members of the County Kerry Field Club visited on 31st March 1945, they found a single surviving circular chamber, six feet in diameter and six feet high, with three short passages leading off it at roughly the cardinal points, and a low crawl passage providing the only way in. The farmer on whose land it stood, a Mr James Scanlon, told the visiting party that there had originally been three such chambers, but that two had been demolished during land clearance. In the process of that clearance he had turned up several boar tusks from the earth. A site note and annotated sketch were produced by a J. McDonnell, who inspected the structure and described it as a hut site with a passage entrance to the south and three niches extending outward. Whether those niches represent the classic branching galleries of a souterrain, or something quite different, remains unresolved. The boar tusks offer a tantalising but uninterpreted detail: animal remains in or near such structures are not unheard of, though their significance here has never been established. There is a further complication in the administrative record: local information gathered in 1986 placed a possible fort at a grid reference that turned out to be wrong, with the actual remains located approximately 140 metres to the south, a small but telling reminder of how easily field knowledge can slip out of alignment with the map.
