By the time the second edition of the Ordnance Survey maps was produced in 1895, the circular enclosure that had once surrounded the site had been so thoroughly altered that it left no trace at all. What remains is a portion of the hut itself, a clochaun, the old Irish term for a small corbelled drystone building, constructed without mortar, its stone courses leaning gradually inward to form a beehive-like roof.

The structure was circular, measuring 3.85 metres across internally, with walls 1.2 metres thick and still standing 1.75 metres high in the surviving section. That combination of thickness and height gives a sense of how solid these buildings once were, designed to last in the wet, wind-scoured conditions of the Dingle Peninsula. When R. A. S. Macalister examined the interior around the turn of the twentieth century, he found shells, animal bones, and traces of burning, the kind of domestic residue that suggests the place was used for habitation or food preparation, possibly over a long period. The first edition of the Ordnance Survey had recorded both the enclosure and the clochaun together, implying a more complete settlement, but whatever that earlier arrangement looked like, it was already being dismantled or disturbed during the nineteenth century.

The site sits within the broader landscape of Corca Dhuibhne, the Dingle Peninsula, an area unusually dense with early stone structures, and the surviving wall section at Cill Mhic An Domhnaigh, modest as it is, belongs to that long tradition of corbelled building that persisted here long after it disappeared elsewhere in Ireland.
