Ireland's second largest medieval cathedral was established by St.Canice as a monastic settlement in the 6th century, William the Earl Marshall built the cathedral on the site in the first decade of the 13th century.Much of the building was carried out between 1215 and 1260. Cromwell's troops wreaked havoc on the cathedral in 1650, but it survived and was restored in the 18th century along with its remarkable limestone grave slabs.
