Cleydael Castle

Cleydael Castle is a fortified castle in Aartselaar with a square layout and four cylindrical corner towers surrounded by defensive moats. The symmetrical design centers on a keep and demonstrates characteristic medieval military architecture.

The fortress was first documented in 1372 under Geeraert van der Elst and withstood a siege by the States General of the Netherlands in 1576. These events mark its endurance as a fortified residence through periods of regional conflict.

The castle served as the seat of the Lords of Cleydael, representing regional noble authority for centuries. Today it embodies the heritage of Flemish landed gentry and their role in shaping local society.

The castle functions as a private event venue and is not typically open for regular tours or visits. The surrounding golf course and grounds offer visitors views of the exterior structures from the estate perimeter.

The rectangular bailey remained surrounded by moats until 1806 before being integrated into the golf course grounds. Today this former outwork houses the clubhouse, uniquely blending medieval fortification remnants with modern recreational use.
