Built around 1424, the fortified castle of Sedan is the largest fortified castle in Europe with a surface area of 35,000 sq m.
Enjoying a strategic position on the eastern border of France, it was constantly extended, reinforced and modernised by the all-powerful La Marck family, Dukes of Bouillon and sovereign princes of Sedan.
The town also enjoys a rich industrial past from its textiles and carpet making activities. Surviving architecture from this period includes the Maison des Gros Chiens and the Dijonval which recall the glorious past of the city. Sedan is the only town with "Ville d'Art et d'Histoire" (Town of Art and History) classification in the Ardennes.
