Cathedral Church of St. Colman and Round Tower from 1873
The diocese was founded in 560 by St Colman. The site for his monastery and monastic school at Cloyne (Irish: Cluain Uamha or "Meadow of the Caves") was donated by Coirpre Cromm mac Crimthainn, King of Munster. The Danes plundered Cloyne in 822, 824 and 885. Cloyne was recognised as a diocese at the Synod of Kells in 1152. The present church dates from 1250 and was built on the site of older buildings. A Roman Catholic cathedral of St Colman was built at Cobh beginning in 1868 and completed in the early years of the 20th century.
