Église Saint-Siffrein
The church of Saint-Siffrein, built between the 15th and 16th centuries, was the cathedral of the diocese of Carpentras until 1790. After the collapse of the nave of the previous Romanesque building, a new cathedral in Gothic style was built from 1404 onwards. The unfinished west façade contains two large 15th-century stained glass windows; the upper part of the façade was covered between 1615 and 1618, and the neo-Gothic bell tower is noteworthy. The nave, supported by buttresses between which side chapels are built, is extended by a narrower and lower choir and a seven-sided apse, a remarkable example of French Southern Gothic.
