What survives is the foundation ring of a subcircular hut, built in drystone, a technique requiring no mortar, relying instead on the careful stacking and interlocking of stones. It sits inside a rath, which is an early medieval enclosed farmstead typically defined by one or more earthen banks and ditches, and its position in the southern half of that enclosure suggests a deliberate spatial arrangement rather than casual placement.

The structure has an internal diameter of 6.2 metres, modest but functional as a domestic or agricultural space, with what appears to be an entrance on the north-west side. The interior is now filled with collapsed stone, and a notably dense scatter of material presses against the outer face at the north. This kind of accumulation can indicate the slow decay of a wall that was once considerably higher, the stones gradually spilling inward and outward over centuries. The place name 'Cloghaun' derives from the Irish 'clochán', meaning a small stone building or beehive hut, a form found in various early Christian and pre-Norman contexts across Kerry and the wider west of Ireland. That the maps preserve this name at all, even tagged as a 'site of', suggests local memory of the structure outlasted its last standing stones by some margin. The survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan, published by Cork University Press in 1996, recorded the foundations as part of a wider effort to document the archaeological landscape of South Kerry, a region unusually dense with early remains.
