Kilrush Church

Kilrush Church is a rectangular stone ruin in Limerick built with large blocks of stone and featuring a distinctive lintel. The structure shows typical medieval construction methods with solid masonry and simple architectural details.

The ruin was built in the 10th century and remains the oldest standing building in Limerick. First documented mentions appear in 1201, marking its role as an important religious center in the medieval city.

The church honors Mainchín mac Setnai, a 6th-century Irish saint, and reflects early Celtic Christian traditions that took root in this region. The dedication shows how medieval communities here connected to their own holy figures.

The ruin is located west of Limerick city center and remains open for visits and historical study. Visitors should be aware this is an archaeological site and respect it as a place of historical importance.

Archaeological excavations in 1999 uncovered human remains beneath the Quinlivan window dating to the 16th and 17th centuries. This discovery provides rare physical evidence of burial practices from those later centuries at the site.
