They are low, barely ankle to shin height in places, and together they measure only a few metres on each side. Yet the perpendicular junction of the two sections, and the way they are built with a double face, meaning stones laid on both sides of the wall with a core between them, is enough to suggest that what remains is the corner of a rectangular building, oriented roughly northeast to southwest, that once stood close against the inner face of the cashel enclosure.

A cashel is a roughly circular stone-walled enclosure, the dryland equivalent of a crannog, typically associated with an early medieval farmstead or small settlement. The cashel at Ballyshanny, into whose interior these wall fragments belong, forms the broader context for this small structure. The building sits in the north-northwest sector of that enclosure, tucked near the cashel wall, which is exactly where ancillary structures, byres, stores, or sleeping quarters, are sometimes found in comparable sites elsewhere in Ireland. The walling itself is double-faced, with the two surviving sections running 4.3 metres and 4.1 metres respectively, and a width of around 0.75 metres. Beyond that geometry, the structure gives little away. No date can be attached to it with any confidence, and whether it was domestic, agricultural, or something else entirely remains an open question.
