The cathedral of Vaison was built on the ruins of a Roman temple, the remains of which can be seen outside the chevet. More than one church has existed on this site; a 6th-century basilica was destroyed by Frankish invaders.
The present building dates primarily from the 11th and 12th centuries. After a dispute with the Count of Toulouse in the late 12th century, the medieval city of Vaison was mostly abandoned for the new town. Today, little remains of the extensive medieval city except for the cathedral.
The apse is the most interesting aspect of the interior. Behind a simple stone altar, on a lower level than the nave, is the medieval bishop's throne and three semicircular benches for the canons. In front of the throne is an old sarcophagus containing the relics of St. Quenin (d. 578). The apse also contains several tomb niches of various styles and some reliquaries and statues.
The cloister, dating primarily from the mid-12th century, is a peaceful space with a lush central garden. The canons' buildings, such as the refectory and dormitory, have disappeared and many of the capitals were restored in the 19th century, but the cloister retains its medieval appearance and atmosphere. Most of the capitals are carved with foliage and vines, but some have charming creatures and human faces.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
