The Cathedral of the Church of Christ, and officially the Holy Trinity Cathedral in Waterford, is an 18th century temple belonging to the Church of Ireland. It is a neoclassical building with a square neo-gothic tower. The interior is decorated with neoclassical stucco and wooden decorations.
The cathedral was built between 1773-1779 on the site of an earlier cathedral and church during the Normandy invasion. It was the temple where the Norman chief Strongbow was married to the Irish princess Aoife. The cathedral was designed by John Roberts.
It is a three-nave structure with regular proportions, three-nave, with an extended vestibule. The entrance is decorated with a columned portico topped with a tympanum. Above it there is a neo-Gothic, stone, square tower with a high spire. The interior is divided into aisles by columns with gilded capitals. On the ceiling you can see stucco plant decorations. Similar ones are repeated in wood on the elements of church furnishings.
