They are modest in scale, barely over a metre in height, yet the technique that holds them together is ancient and deliberate: corbelled drystone construction, where stones are layered so that each course projects slightly inward over the one below, eventually closing to form a roof without mortar or timber. A lintelled passage, a short opening spanned by a flat capstone, connects the two chambers. The larger of the pair, to the south-west, appears to contain a wall-passage or wall-chamber, a recess built into the thickness of the stone itself.

The dimensions are tight. The smaller structure measures roughly two to two and a half metres across; the larger runs to about three metres in diameter. Wall thickness reaches 1.2 metres in places, which partly explains how these structures maintain their height of 1.3 metres despite centuries of exposure on an open mountainside. Corbelled buildings of this kind are scattered across the Dingle Peninsula, the most famous being the beehive huts, or clochán, associated with early Christian monastic settlements, though not every corbelled structure on the peninsula carries a religious or monastic explanation. J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region, which covers this part of the Dingle Peninsula, catalogued this site and noted the basic form without resolving its precise function or date.
