Château de Vianden

Vianden Castle was constructed between the 11th and 14th centuries on the foundations of a Roman castellum and a Carolingian refuge, and is one of the largest and most beautiful feudal residences of the Romanesque and Gothic periods in Europe. Until the early 15th century it was the seat of the powerful counts of Vianden, who maintained close ties to the French royal family and the German imperial court. After falling into ruin in the 19th century, the castle was transferred to State ownership in 1977 and has been restored as a monument of European rank — recognised by CNN among the most beautiful castles in the world.
