This cathedral replaced the ancient cathedral on the Rock of Cashel and the medieval parish church of the town to become one of two Anglican cathedrals built in Ireland or Britain in the eighteenth century, the other being at Waterford. Its Georgian style is evidenced by the regular form, hipped roof and round-headed openings and by the incorporation of Classical elements such as the aedicule, pediment and pilasters. There is evidence of fine stone crafting throughout the building. The spire was added by Vitruvius Morrison in 1812, the chancel was remodelled in a gilded elaborate Italian Romanesque style by William Atkins and the organ is by Samuel Green. The curiously unfinished south side of the entrance front, and the different elevations to the long north and south walls, are all of particular interest and perhaps reflect a desire to lavish attention on the parts of the building immediately visible on the approach from John Street. It forms a nationally important precinct with the library, gates and gate lodge. The tall spire ensures that the building is visible from afar and constitutes one of the most imposing features in the Cashel townscape.
