History

Carved out of the diocese of Poitiers in 1317, the Diocese of Luçon (Latin: Dioecesis Lucionensis; French: Diocèse de Luçon) covers the department of Vendée, with its seat at the cathedral of Nôtre-Dame in the commune of Luçon. The French Revolution interrupted the existence of this Latin Church diocese of the Catholic Church in France, and only in 1821, after the Bourbon restoration and a new concordat with the Holy See, was it restored.

What is kept by invitation

The record above is published because it is public: what this see is, when it was erected, who holds its chair, and where it stands among its neighbours.

The working record is not. The chancery's address, telephone and email, the clergy of the see, and the hours of Mass, confession and adoration in the parishes within it are kept for members, and a person reads every request.
