Bouillon Essentials

Bouillon is defined by its strategic location within a sharp loop of the Semois river in the Ardennes. The town's skyline is dominated by the medieval Bouillon Castle, a fortification with roots dating back to the 10th century. Cultural landmarks include the Musée Ducal, which houses collections on the Crusades and regional history, and the Archéoscope Godefroid de Bouillon. Natural perspectives of the landscape are provided by the Belvédère d'Auclin and the Tomb of the Giant, a classified natural site featuring a dramatic river meander.
