St Patrick's Cathedral, Dublin
Saint Patrick's Cathedral () in Dublin, Ireland, founded in 1191, is the National Cathedral of the Church of Ireland. With its spire, St. Patrick's is the tallest church (not Cathedral) in Ireland and the largest. Christ Church Cathedral, also a Church of Ireland cathedral in Dublin, is designated as the local Cathedral of the diocese of Dublin and Glendalough.
Cathedral of the Most Holy Trinity, Waterford
The cathedral was designed by John Roberts (Waterford architect) in 1793 and has the distinction of being the oldest cathedral of the Roman Catholic Church in Ireland. A chapel had previously stood on the same ground, having been constructed there at the height of the Penal Laws on the request of the Roman Catholic community of Waterford.
In the early part of the twentieth century, railings separated the church from the street. These have since been removed. The Cathedral was refurbished in 1977 and a new altar was installed so that Mass could be celebrated "ad populum" (facing the people). A gift of ten crystal chandeliers from Waterford Crystal enhanced the glory of the Cathedral. A complete reflooring of the building and a restructuring of the sacristy took place in the early 1990s. Further work was completed in November 2006 with a re-fit of structure to the interior and exterior.
