The Citadel of Dinant (Citadelle de Dinant) was built in 1815 on a site which was originally fortified in 1051 when the region was ruled by the Prince-Bishopric of Liège. The citadel overlooks the city of Dinant and the strategic Meuse river which runs through the town. It is open to the public.
Together with Huy, Liège and Namur, the Citadel of Dinant forms part of the so-called Meuse Citadels.
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.
