A disciple of St. Carthage, called Molana, founded a little monastery - Abbey of St. Molanfide - on an island called Dair Inis on the River Blackwater - north of Youghal. The ruined abbey is home to the remains of Raymond le Gros, one of the first of the invading Norman knights to come to Ireland, who died in or around 1186. It was extensively rebuilt in the 13th century and became an Augustinian abbey, when it is claimed that the Abbey had an international reputation for scholarship.
