Notre-Dame Cathedral in Saint-Paul-Trois-Châteaux, a French commune in the Drôme département in the Auvergne-Rhône-Alpes region, was the episcopal see of the former bishopric of Saint-Paul-Trois-Châteaux. The church was built in the 12th century and is an example of Romanesque architecture in Provence.
The name Saint-Paul is reminiscent of a saint born in Reims in Champagne, the 372 as successor of St. Torquatus was bishop of Tricastin and was buried in the cathedral after his death in 412. Nothing is preserved of this first church. Also from the 852 mentioned cathedral, the Maria and the St. Paul was consecrated, there were no traces after the invasions of the Germans, the Saracens and the Hungarians.
The construction of today's church is dated to 1120. First, the choir and the transept were built. By 1180, the nave was completed as well as a large part of the sculpted decor and the vaulting.
During the religious wars, the church was badly damaged. As a result of the Concordat of 1801, the diocese of Saint-Paul-Trois-Châteaux was dissolved and divided between the Archdiocese of Avignon and the diocese of Valence. In 1840 the church was added to the list of monuments historiques as a protected monument. Wikipedia
