Walzin Castle stands majestically on a steep rocky promontory above the Lesse River near Dinant, its Gothic Revival architecture rising dramatically from the landscape. Dating back to the 11th century with significant construction in the 13th century, the castle showcases a 15th-century Renaissance horseshoe tower with cannon ports, remnants of its strategic military heritage. Though privately owned and not open to the public, the castle's striking silhouette captivates visitors kayaking on the river or hiking the surrounding trails, and guided walks are available during summer months. Damaged by French forces in 1554, it was beautifully restored in the early 20th century under architect Octave Flanneau, combining historic fortification design with neo-Gothic elegance.
