St Mary's (also known as Limerick Cathedral), is a cathedral of the Church of Ireland in Limerick city, Ireland which is dedicated to the Blessed Virgin Mary. Previously the cathedral of the Diocese of Limerick, it is now one of three cathedrals in the United Dioceses of Limerick and Killaloe. The cathedral is open to the public throughout the week, subject to church services. Limerick Cathedral dedicated to the Blessed Virgin Mary was founded in 1168 and is the oldest building in Limerick which is in daily use. It has the only complete set of misericords left in Ireland. The Cathedral has seen many changes as the city expanded around it and it remains today the oldest and most historic building in Limerick. No trip to the City is complete without visiting this historic building at the very heart of this ancient metropolis.
