The structure measures about 5.4 metres in diameter, with a wall that would originally have stood perhaps half a metre high and roughly three metres thick, the kind of substantial construction that suggests it was meant to last. The best-preserved stretch runs from the north-east around to the south-south-east, and a gap in the walling at the north-east is thought to be the original entrance.

The site has a local name that connects it to a specific tradition of small enclosures in the Irish landscape. It is recorded as a 'cathairín', a diminutive of 'cathair', a term used in Munster for a stone-walled enclosure or ringfort-type structure, though in diminutive form it often describes something modest and domestic rather than defensive. By the 1940s it was already being noted as a feature of Patrick Sweeney's land, which places it in a broader mid-twentieth-century effort to document the rural archaeological landscape before further change could obscure it. A second possible hut site lies roughly 110 metres to the north-north-east, which raises the quiet possibility that this stretch of hillside was once occupied by more than one such structure, though the relationship between the two, if any, remains unclear.

The Paps of Dana themselves are a pair of distinctive rounded summits long associated in Irish mythology with the goddess Anu, and the surrounding landscape carries a density of archaeological features that reflects centuries of human activity on these slopes. This particular hut, half-buried in pasture, is easy to overlook precisely because it has settled so completely into the ground around it.
