Ancient Diocese of Boulogne


The former French Catholic diocese of Boulogne existed from 1567 to the French Revolution. It was created after the diocese of Thérouanne was suppressed because of war damage to the see; effectively this was a renaming. The Concordat of 1801 suppressed the diocese of Boulogne, transferring its territory to the diocese of Arras. The seat was the Boulogne Cathedral, demolished in 1793.
