The structure is modest even by the standards of early Irish hut sites: just two metres in diameter, with a wall that was never much more than half a metre thick and now barely reaches forty centimetres above the surface of the surrounding bog. The narrow entrance, less than half a metre wide, faces north-east, and the interior, though level, is partly choked with fallen rubble.

Hut sites of this kind are among the more enigmatic features of the Irish archaeological landscape. Small, drystone-walled, and often found in upland or marginal terrain, they are associated broadly with early medieval settlement and seasonal pastoral activity, though pinning down precise dates without excavation is rarely straightforward. What makes the Crossterry site quietly interesting is its context. Roughly five metres to the west lies a separate enclosure, and about ten metres to the north stands another hut site of the same general type. The clustering suggests this was not an isolated structure but part of a small complex, perhaps a farmstead or a seasonal grazing station where people, animals, and basic shelter occupied the same patch of hillside together. The bog has done its slow work since, gradually consuming the lower courses of the walls and softening the outlines, but enough protrudes above the surface to make the form legible.
