The castle was constructed primarily of brick, which was a transition from traditional stone building techniques of the era.
It survived the Siege of Brussels in 1489, though it suffered significant damage during the conflict.
The castle was famously featured in the Flemish comic strip 'The Seven Bridges' by Willy Vandersteen.
The defensive walls feature original arrow slits and crenelations designed for archery defense.
The moat system was originally connected to the local Zenne river to provide a constant water supply for defense.
The structure changed owners multiple times, serving as both a military garrison and a private textile factory in the 19th century.
Kasteel van Beersel is one of the few remaining examples of late-medieval military architecture in Belgium. The site features a water castle protected by a double moat and three imposing brick towers. Built in the 15th century, the structure served as a defensive fortress for the city of Brussels against threats from the Duchy of Brabant. It transitioned from a strategic stronghold to a residential manor, eventually falling into decay before its 20th-century restoration. Visitors can explore the preserved ramparts, the attic floors, and the internal living quarters. The castle remains surrounded by a moat that retains its original layout. It is located in the Zenne Valley, south of Brussels, within the Green Belt region.

Check the official website for event dates, as the castle occasionally hosts historical reenactments.
