Château de Walhain, Medieval castle ruins in Walhain, Belgium.
Château de Walhain is a castle ruin in Belgium situated where two rivers meet. A cylindrical stone tower and corner remains indicate the structure's original form, with the double moat system still traceable in the landscape.
The castle was built in the late 1100s under Duke Henry I of Brabant to defend against claims from Namur County. It served as part of a network of fortifications that reflected power struggles in the region for centuries.
The name reflects the two rivers converging at this location, which shaped medieval defense strategies. The remaining structures still reveal how people adapted their lives to this strategic riverside setting in the Middle Ages.
Access to the ruins is arranged through the Walhain Tourist Office, which coordinates visits and provides on-site guidance. The site is walkable along both riverbanks, though it can become slippery during wet weather, so sturdy footwear is advised.
This is the only surviving lowland castle in the region, a rare example of medieval river defense design. Its location is unusual because most castles of that era were built at higher elevations.
