Although this building pales in comparison to the nearby Palais des Papes, the Cathedral of Notre-Dame des Doms is still worth a visit. 

This beautiful 12th-century cathedral has a serene Romanesque interior. Upon entering through the main doorway, visitors will notice the remains of frescoes by Simone Martin. Inside the cathedral, there is an inspiring sense of space and intimacy. 

In the crossing to the left stands a 12th-century bishop's chair of white marble; in the first side chapel on the north is the former Romanesque main altar. The fourth chapel on the south side houses a Late Gothic monument to John XXII.

 In the Baptistry Chapel, early 15th-century frescoes adorn the walls. The frescoes portray the Baptism of Christ. A silver sculpture of the Scourging of Christ is found in the north aisle. On the cathedral's exterior, a splendid gilded statue of the Virgin crowns the tower with her hands outstretched to welcome the faithful.
