At Clone in County Wexford, what survives is not a building but the recorded original location of a window embrasure, the splayed recess cut into a wall to hold a window and allow light to angle into a church interior. The significance of this particular feature is that it may not have begun its life where it was later found. The embrasure in question appears in the south chancel wall of St. Peter's Church in the nearby town of Ferns, but the suspicion is that it was not made for that setting at all.

The working theory, recorded by researcher Michael Moore, is that the stonework originated in a Romanesque church at Clone. Romanesque architecture, which flourished in Ireland roughly between the twelfth and early thirteenth centuries, is recognisable for its rounded arches, decorative carving, and carefully worked stone details. If the embrasure did come from the Clone church, it would represent a piece of that earlier building that was removed and reused at Ferns at some later point, a practice that was common enough in medieval and post-medieval Ireland, when dressed or carved stone from a ruined structure was too valuable to leave untouched. Ferns itself was a place of considerable ecclesiastical importance in medieval Leinster, which makes the movement of architectural material toward it entirely plausible, though the connection in this case remains tentative rather than proven.
