The former Breton and French Catholic Diocese of Saint-Malo (
Latin: Dioecesis Alethensis, then Dioecesis Macloviensis) existed from at least the 7th century until the
French Revolution. Its seat was at
Aleth up to some point in the 12th century, when it moved to
Saint-Malo. Its territory extended over some of the modern departments of
Ille-et-Vilaine,
Côtes-d'Armor, and Morbihan. Until the 860s, it was often termed the bishopric of
Poutrocoet.
