Between Provence and Dauphiné, dominating the cluse where the Durance flows, the Citadelle of Sisteron dominates the sky, crowning the town with its walls, bastions and keep. The view from here is breathtaking, stretching for 150 km and offering one of the finest vantage points in Haute Provence. It bears witness to eight centuries of architecture and history. The keep and sentry walk, built on the narrow rocky spine, date back to the 12th century. The tiered bastioned enclosures dating from the 16th century of the Vauban project, designed in 1692, only the powder magazine was built.
Major alterations were carried out on the north face in the mid-19th century. It was at this time that the magnificent underground staircase linking the fortress to the town was carved out of the rock.
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.
