It almost certainly did not. The piece is one of several architectural fragments gathered inside the church, the kind of modest assemblage that appears when earlier structures are demolished or fall into ruin and their carved stonework is salvaged rather than lost entirely.

Scroll carvings of this type were a common decorative motif in Irish ecclesiastical architecture, used to ornament doorways, chancel arches, and window surrounds across the medieval period. When the buildings that originally housed them were altered or collapsed, individual stones sometimes found a second life set into later walls, their original context gone but the carving itself preserved. That seems to be the case here. The fragment at Patrickswell sits alongside other displaced pieces inside the church, a small cluster of stonework that records, in a fairly oblique way, that something older once stood nearby or was incorporated into the fabric of the building over time.
