Franchimont Castle, Theux, used to be one of the twelve residences and strongholds of the Liège bishop which defended the east of the principality from the 11^th– 12^th century onwards.

Despite the destructions that occurred during the French Revolution at the end of the 18^th century, the ruins that remain are still impotent. Visiting them allow visitors to understand the evolution of military architecture and how it matched the armament, particularly the influence of black powder artillery. Several elements of the castle’s structure remain and/or have been restored: dungeon, pillboxes, squirrel-cage crane, bread oven, guard room, etc.

The site is the property of the municipality of Theux. Tourism management and volunteer restoration are the responsibility of the association “Franchimont Companions” (Les Compagnons de Franchimont, in French).

Many searches and archeological studies have been led on the castle’s site. The conservation of the site combines searches and archeological studies with coherent and durable restoration projects in order to preserve this exceptional patrimony the best possible way.
