The Diocese of Bayeux and Lisieux (Latin: Dioecesis Baiocensis et Lexoviensis; French: Diocèse de Bayeux et Lisieux) is a Latin Church diocese of the Catholic Church in France. It is coextensive with the Department of Calvados and is a suffragan to the Archdiocese of Rouen, also in Normandy.
With the Concordat of 1802, the former Diocese of Lisieux was merged with that of Bayeux. A pontifical brief in 1854 authorized the Bishop of Bayeux to call himself Bishop of Bayeux and Lisieux.
The Archdiocese of Bordeaux (–Bazas) (Latin: Archidioecesis Burdigalensis (–Bazensis); French: Archidiocèse de Bordeaux (–Bazas); Occitan: Archidiocèsi de Bordèu (–Vasats)) is a Latin Church ecclesiastical territory or archdiocese of the Catholic Church in France. The episcopal see is Bordeaux, Aquitaine. It was established under the Concordat of 1802 by combining the ancient Diocese of Bordeaux (diminished by the cession of part to the Bishopric of Aire) with the greater part of the suppressed Diocese of Bazas. The Archdiocese of Bordeaux is a metropolitan see, with four suffragan dioceses in its ecclesiastical province: Dioceses of Agen, Aire and Dax, Bayonne, and Périgueux.
