It is modest to the point of near-invisibility, the kind of structure that archaeological survey work routinely rescues from obscurity before it is swallowed by development or simply overlooked as a natural formation. What makes it quietly interesting is the way it was built: not just placed on the hillside, but integrated into it.

The structure was identified by John Cronin and Associates during pre-development survey work ahead of a wind farm at Grousemount. Measuring roughly 3.8 metres east to west and 3.5 metres north to south, it was constructed from random, loose dry-stones, the technique of laying unworked stone without mortar that was used across Ireland for millennia in shelters, field boundaries, and enclosures of every kind. The west wall survives to eight courses and stands 1.2 metres high, making it the best-preserved section. The south wall has been reduced to one or two courses. On the north side, a formal wall is barely distinguishable at all; the builder appears to have cut into the hillside and made use of natural rock outcroppings, letting the landscape do the work. The craggy higher ground to the east and northeast would have provided natural shelter, while the interior floor sits at roughly the same level as the ground outside. A probable entrance occupies the northeast corner, where the east wall stops short at 2.1 metres. Curving out from the northwest corner, a low arc of earth and stone, no more than 0.6 metres high, may represent a small annex or outwork of some kind.

No date has been assigned to the structure, and its precise function remains uncertain. The combination of a sheltered aspect, an outward-facing view across the Roughty valley, and the pragmatic use of the natural terrain suggests a utilitarian purpose, possibly a seasonal shelter for a person or animals working the upland ground. Its discovery, made possible only by survey work tied to a commercial development project, is a reminder of how many such small structures remain unrecorded across Kerry's uplands.
