They are door hanging eyes, one on each jamb, and they date from the late medieval period. In themselves they are modest objects, the kind of hardware that once held a heavy timber door in place, but their survival embedded in standing masonry, in the middle of a busy county town, is the quietly unusual thing.

Door hanging eyes are the fixed counterparts to the hooks or pintles on which a door's hinges pivot, part of a hanging system common in medieval and early modern Irish buildings before modern hinge designs became standard. That this pair remains in situ, rather than having been removed during later construction or renovation, suggests the arch they occupy has survived with unusual completeness. The site sits within the historic core of Ennis, a town with a substantial medieval inheritance centred on its Franciscan friary, and the retention of such a small functional detail within that built fabric is a minor but genuine piece of continuity across several centuries.
