St. Canice's Cathedral, and watchtower
The present building dates from the 13th century and is the second longest cathedral in Ireland, after St. Patrick's Cathedral, Dublin. Beside the cathedral stands a 100 ft 9th-century round tower. St Canice's tower is an example of a well-preserved 9th-century "Celtic Christian" round tower. It is dedicated to St Canice. It is one of only two such medieval round towers in Ireland that can be climbed to the top.
