Rectangular in plan and roofed with flat slabs laid horizontally, it measures just 1.8 metres north to south and 1.1 metres east to west, which is to say roughly the footprint of a large wardrobe. Whatever its original purpose, it has been granted a place in the archaeological record, though the honest caveat attached to its description is that the site was never actually visited by those who catalogued it.

The structure lies some 70 metres south-south-east of Clochán an Phúca, a clochán being a type of dry-stone beehive hut associated with early medieval Ireland, often found in clusters on the western seaboard. That proximity is worth noting, since it places this small slab-built box within a landscape already marked by vernacular stone construction. Archaeologist J. Waddell, whose note is attached to the record, suggested it may have functioned as an animal shelter rather than any kind of human dwelling, which seems plausible given its dimensions. Whether it dates to the same broad period as its neighbour, or represents something more recent and purely functional, remains an open question.
