Bouillon Castle

Bouillon, Belgium, Belgium

---

Bouillon Castle in Bouillon, Belgium, is a medieval fortress located on a rocky spur within a sharp bend of the Semois River, with origins dating back to at least the 8th century. 

It played a crucial role in medieval history as the ancestral seat of Godfrey of Bouillon, a leader of the First Crusade, who sold the castle to finance his expedition to the Holy Land. The castle was fortified and expanded over the centuries, notably strengthened by the famous military architect Vauban in the late 17th century, adapting it for heavy artillery.

Its massive stone walls, towers, and drawbridges represent its strategic defensive importance, controlling key trade routes and regional power. Although its military significance declined over time, Bouillon Castle remains one of Belgium's largest and most impressive fortifications, attracting visitors for its rich history, medieval architecture, and panoramic views of the Semois River
