Designed by local architect John Roberts, this is one of the architectural gems of Waterford. In 1773 the old Norman Gothic Cathedral was demolished after pressure was brought on the local bishop by the City Corporation. The old cathedral was so strongly was it built that gunpowder had to be used in its demolition. The present Cathedral was begun in 1773 and was completed in 1779 at a total cost of £5,397. The exterior is notable for its wonderful tower and spire with its classical detailing. The cathedral has a fine Georgian galleried interior.
