The Diocese of Mondoñedo-Ferrol (also known as "Dioecesis Mindoniensis-Ferrolensis") is one of the five districts in which the Roman Catholic church divides Galicia in North-western Spain. The bishop who has two Cathedrals (i.e.: from Latin "cathedra" meaning seat, so two "seats") one in Ferrol and the other in Mondoñedo has jurisdiction over the most northern parishes of Galicia; covering the parishes of the northern part of the Province of A Coruña and the Province of Lugo. The area had previously been home to Britonia, a settlement founded by expatriate Britons in the wake of the Anglo-Saxon invasion of Britain. Britonia was represented by the diocese referred to as Britonensis ecclesia (British church) in sources from the 6th and 7th centuries.
