That alone makes it unusual. Roofed vernacular structures of this kind are rare survivals; most have long since collapsed into rings of tumbled stone, their original form left to imagination. This one has held together, its walls and covering still legible as a complete space.

The construction technique is corbelling, a method in which each successive course of stonework is laid slightly inward over the one below, until the courses eventually meet at the top without the need for any timber or mortar. It is a technique with an exceptionally long history in Ireland, associated most famously with early medieval clochán structures, though corbelled building persisted in vernacular and agricultural contexts well into more recent centuries. This hut is considered probably fairly recent in date, which in practice likely means the nineteenth century or thereabouts rather than anything prehistoric. The walls rise vertically to 1.7 metres before the corbelling begins, and the interior measures roughly 1.54 by 2.08 metres, with a total height of 2.16 metres. It is irregular in shape, built of drystone, meaning no mortar, just carefully selected and stacked stone. At that scale it would have sheltered a person, perhaps a shepherd working the hill grazing, or offered temporary storage. The structure sits on a shoulder of the slope, a position that would have given some shelter from the prevailing weather while keeping a view across the land below.
