Measuring just 1.4 metres long, 0.9 metres wide, and 0.6 metres high, it is roofed by three flat lintels and opens through an entrance on its southern side. It is a drystone construction, meaning no mortar binds it together; the stones rely entirely on their own weight and careful placement to hold their form. What makes it quietly arresting is precisely this combination of miniature scale and deliberate architecture. Someone, at some point, went to considerable trouble to build something very small, very carefully.

The structure sits in the shadow of a castle recorded nearby, and the two monuments together suggest a landscape that was, at various points, both defended and inhabited in ways that have left only partial traces. The Aran Islands are already dense with prehistoric and early medieval remains, and small ancillary structures of uncertain function, whether storage, ritual, or otherwise, are not uncommon in such settings. This particular example was catalogued by archaeologist Paul Gosling in the Archaeological Inventory of County Galway, published in 1993, which brought systematic attention to monuments across west Galway that might otherwise remain unrecorded. Its function is not specified in the record, and that ambiguity is part of what makes it interesting. It has since been taken into state ownership as a protected national monument.
