Walburg Castle in Sint-Niklaas is a 16th-century moated castle built in 1553 by knight Willem van Waelwijck, named for his wife Walburgis. Surrounded by a picturesque English garden developed during 19th-century renovations by the Van Naemen family, the castle is situated as a serene green oasis within the city center. The castle was acquired by the municipality in 1949 and opened to the public in 1952. Today it houses a stylish bar and restaurant with a welcoming terrace overlooking the pond and fountain, blending historical significance with contemporary leisure, and stands as one of the East Flemish region's most idyllic urban cultural destinations.
