A cashel is a stone-walled ringfort, typically of early medieval origin, and this one is a substantial suboval enclosure. The house sits within it, pressed flush against the cashel's interior, its flat side borrowing the parent wall as one of its own boundaries. That practical arrangement, using an existing structure rather than building freestanding, hints at something deliberate, whether opportunistic reuse or original construction as part of a wider settlement plan.

The outline of the house is defined by a single line of loose stone, forming an internal space measuring roughly eleven metres north to south and nine and a half metres east to west. The D-shape itself is a consequence of the geometry: one curved wall follows the arc of the cashel, the straight edge running along the western interior. No date has been established for it. That uncertainty is not unusual for structures of this kind, where stone-on-stone construction leaves little for archaeological dating methods to work with, and where use and reuse over many generations can blur the original sequence entirely. What remains is the footprint, and the quiet logic of its position within a much larger enclosure.
