Cathedral
St Canice's Cathedral
Ireland's second-largest medieval cathedral (after St Patrick's in Dublin) has a long and fascinating history. The first monastery was built here in the 6th century by St Canice, Kilkenny's patron saint. The present structure dates from the 13th to 16th centuries, with extensive 19th-century reconstruction, its interior housing ancient grave slabs and the tombs of Kilkenny Castle's Butler dynasty. Outside stands a 30m-high round tower, one of only two in Ireland that you can climb.
