Ancient Diocese of Dol

Dol Cathedral

The Breton and French Catholic diocese of Dol existed from 848 to the French Revolution. It was suppressed by the Concordat of 1801.[1] Its see was Dol Cathedral. Its scattered territory (deriving from the holdings of the Celtic monastery, and including an enclave at the mouth of the Seine) was shared mainly by the Diocese of Rennes and the Diocese of Saint-Brieuc.
