In 1589, Maréchal de Villars supervised the construction of a small fort on the hill known as 'colline des Moulins' overlooking Saint-Tropez. This fort was destroyed in 1595, but the military engineer Raymond de Bonnefons chose the same site to build further defensive structures from the start of the 17th century.
The hexagonal tower, which formed an essential part of the village's defence system, was erected between 1602 and 1607. The Citadel underwent numerous modifications over the centuries, before falling into disuse in the 19th century, when the strategic interest of this perfectly-preserved fortress finally diminished.
The old cannons are still in place facing out towards to sea, and the views from the top are stunning across the Gulf and the Mediterranean Sea.
Bought up by the town in 1993 and made a listed monument, today it hosts a museum dedicated to the history of Saint Tropez and its relationship with the sea.
References: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.
