Castle of Seraing-le-Château dominates the village of the same name in Verlaine, Liège, a medieval fortress whose history traces to 911 when the settlement was first mentioned in charter records. The castle itself, built around 1302 by the lords of Haneffe, features high defensive walls and multiple towers reflecting medieval military architecture. The fortress became property of powerful regional nobles including the notorious William I de La Marck, known as the Wild Boar of the Ardennes for his 15th-century campaigns, who frequently sought refuge within its walls. Designated for wellness retreats in modern times, the castle maintains its fortress character and medieval architectural integrity while serving specialized hospitality purposes for contemporary visitors.
