It measures just 3.4 metres east to west and 2.5 metres north to south, defined now by a collapsed drystone wall, a construction technique using stones laid without mortar, whose remains survive to a thickness of around 0.6 metres. Loose stones are scattered across the interior, but the most quietly telling detail is structural: the northern portion of the floor was cut roughly 0.6 metres into the hillside, while the southern portion sits raised by about 0.2 metres, a deliberate compensation for the natural slope that speaks to someone who knew exactly what they were doing when they built here.

This kind of small, unroofed stone enclosure is not uncommon in the uplands of Kerry, where generations of people used the hills seasonally for grazing, cutting turf, or simply moving through. The hut site does not sit in isolation. An enclosure lies approximately 14 metres to the south, and a second hut site is roughly 12 metres to the east, suggesting this was not a solitary refuge but part of a small cluster of structures, a pattern consistent with the kind of seasonal pastoral settlement, known in Ireland as booley activity, where families or herders would move livestock to higher ground in summer months. The mountain itself, Mangerton, rises above the lakes of Killarney and its slopes have been used by people for a very long time, though the precise date of this particular site is not recorded.
