Bouillon Castle is a medieval fortress in the Belgian Ardenne, standing majestically on three rocky peaks overlooking the town of Bouillon and the Semois river. With over 1,000 years of documented history, the castle is remarkably extensive, measuring approximately 340 meters in length with its highest point rising 75 meters above the river. The Austria Tower offers 360-degree panoramic views, while visitors can explore the drawbridge, underground passages, and historic rooms including torture chambers and Godefroy Hall. The castle welcomes around 135,000 visitors annually and features a scriptorium museum, falconry displays, guided tours, torchlit explorations, and a sound and light show exploring its medieval history.
