Modave Castle, one of Wallonia's most scenic and visited castles, perches on a 60-meter rocky outcrop overlooking the Hoyoux river and valley within a 450-hectare nature reserve. Though the structure likely originated in the late 13th century, its present appearance reflects the extensive restoration undertaken by Count Jean-Gaspard-Ferdinand of Marchin between 1652 and 1673, featuring Renaissance architecture and beautiful Italian-style gardens. The interior spans 25 rooms across basement, ground, and first floors, containing exquisite stucco, 17th-century tapestries, faience from Gien, and 19th-century Val-St-Lambert crystal, with audio guides available in 8 languages. Currently owned by Vivaqua, which manages the springs and wells in the surrounding park, the castle continues restoration efforts while welcoming visitors from around the world.
