St. Patrick’s Church is said to have been established by St. Patrick, after a local chieftain offered him a site for a church on the north bank of the River Bann in the 5thcentury. Patrick is said to have chosen a spot covered in ferns, giving rise to the name Cuil Raithin which became the name of the town of Coleraine. A church is known to have existed on the site from at least the medieval period.
