Its walls, built in the drystone tradition where stones are laid without mortar and rely entirely on their own weight and careful placement, stand only about 40 centimetres high and are similarly narrow. The structure measures just 4.5 metres on its longest axis and 2.4 metres across, making it barely large enough to crowd a handful of animals together. An entrance gap opens to the north-northeast, and traces of what appears to have been an outer wall survive to the east and northeast.

This is a sheepfold, a working enclosure used by upland farmers to gather, sort, or shelter sheep, typically during lambing, shearing, or before driving animals to market. Such structures were built as needed, from whatever stone lay nearby, and rarely recorded or remarked upon. What makes this particular example quietly interesting is its setting and its survival. The plateau above Lough Aganny is the kind of ground that rewarded summer grazing and demanded seasonal labour, and the fold preserves in miniature the logic of that work: a contained space, a controlled entrance, the suggestion of an outer pen where animals could be held before being moved inside. The outer wall fragments hint at a slightly more organised arrangement than a single ring of stones would imply.
