Nothing about its current function suggests anything unusual, but a closer look reveals a small upstand running along one face, a narrow ridge of between half a centimetre and two centimetres, precisely the kind of lip that would have held a window frame in place when the stone lay horizontal in a building. Someone has drilled a hole near the top to take a gate latch, which sits there now with a quiet disregard for the object's origins. The dressed face that looks out over the road carries vertical line finishing, the kind of neat, deliberate stonework applied to surfaces meant to be seen from the outside of a structure. The opposite narrow side is left rough, exactly as it would have been buried within the surrounding masonry.

The stone was identified in 1997 during the North Munster Project of the Discovery Programme, a systematic fieldwork initiative that documented archaeological and architectural features across the region. What the surveyors recorded was a window sill, cut from limestone and measuring just over a metre in height, thirty-six centimetres wide, and ten centimetres thick, that had been removed from its original building at some unknown point and repurposed as a field gatepost. This practice of reusing dressed stonework from ruined or demolished structures was common across rural Ireland, where cut stone was a valuable material not lightly wasted. The building it came from has not been identified, but the quality of the dressing suggests it was no casual construction. The sill has been set with its formerly horizontal face turned inward toward the gate entrance, so the upstand that once kept rain from running beneath a window frame now simply faces the field.
