It measures just over five metres across in both directions, and what survives of its wall, still standing to around 1.2 metres in places and nearly 1.4 metres thick, tells a more complicated story than its modest dimensions might suggest.

The best-preserved section runs from the south-east to the south-west, where the masonry is faced on both the internal and external sides with well-constructed uncoursed stonework, the gap between those faces packed with smaller rubble. The detail that draws most attention is along the southern arc: at roughly a metre above ground level, both wall faces begin to slope inward by about ten centimetres. That inward lean, combined with the substantial volume of collapsed rubble on the ground, points toward the possibility that this was once a corbelled hut, known in Irish as a clochán. A clochán is a dry-stone structure roofed without mortar or timber, the courses of stone gradually projecting inward until they meet at the top, a technique with ancient roots in Ireland and particularly associated with the western seaboard. The north-east sector of the wall has almost entirely disappeared, leaving only the internal foundation course of larger stones and faint traces of the external base. Elsewhere, a more recent linear wall was built across the interior, likely using stone robbed from the collapsed south-west arc, and a break in that later wall suggests the enclosed south-east sector was put back to use at some point as a simple animal shelter, the original structure quietly repurposed long after whoever built it was gone.
