Kasteel Cleydael, a moated castle in Aartselaar near Antwerp, represents late medieval water fortification architecture with a square tower and three round corner towers. Evidence suggests the castle existed as early as 1259, with portions dating to the 14th century, making it one of Flanders' oldest continuously-referenced fortifications. Strategically positioned on an island created by two branches of the Benedenvliet river, the castle originally served defensive purposes for the lords of Cleydael. Following 17th-century renovations by Antwerp mayor Frans Paschier van den Cruyce, the castle evolved into an elegant residence. Today, the castle serves as a private event venue, with surrounding lands managed by a golf club, offering a distinctive setting for celebrations.
