St Mary's Cathedral is the older of Limerick's two cathedrals and dates from the 12th century. The cathedral has elements of both Romanesque and Gothic styles of architecture with Romanesque arches and doorways and Gothic windows. The plan and elevation of the cathedral show signs of the design being an altered over the years. The original plan of the church was in the form of a Latin cross. Additions were made to the Cathedral during the episcopate of Stephen Wall, Bishop of Limerick. The Romanesque doorway on the west side is an impressive carving of chevrons and patterns. Like many medieval churches in Ireland, the building has been heavily restored by the Victorians. The Cathedral plays a dominant role in this medieval area within Limerick City showing the amalgamation of the architectural styles of Romanesque and Gothic. The tower of St. Mary's Cathedral was added in the 14th century, and it rises to 120 feet
