Sisteron Cathedral, now the Church of Notre-Dame-des Pommiers, was formerly a cathedral, and is a national monument.
The cathedral, dedicated to the Blessed Virgin Mary and Saint Thyrsus, was the seat of the Bishops of Sisteron, who had a second seat at Forcalquier Cathedral. The bishopric was abolished under the Concordat of 1801 and merged into the Diocese of Digne.
The Romanesque building, one of the most sizeable religious structures in Provence, was built between 1160 and 1220.
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.
