of Munster, Domnall was purportedly buried in the cathedral, with the remnants of his stone coffin still visible in the Cathedral chancel. Bishop Cornelius O'Dea is buried alongside several other Bishops of Limerick in what is believed to be an Episcopal vault underneath the chancel itself. Also notable are the Sexton, Barrington, Boyd and Vanderkiste tombs along the south entrance pathway. From the Irish Reformation to the 19th century There are five chandeliers which hang from the ceiling. These are only lit on special occasions. The larger three of the five were made in Dublin and presented in 1759 by the Limerick Corporation. The belfry holds a peal of eight bells, six of which were presented by William Yorke, mayor of Limerick, in 1673. An active team of bell ringers travels the country to compete with other campanologists. Saint Mary's received its organ in 1624, when Bishop Bernard Adams donated one. It has been rebuilt over the centuries and was most recently renovated in 1968 and 2005.
