Kasteel Woerden, Medieval fortress in Woerden, Netherlands.
Kasteel Woerden is a medieval castle in the center of the Dutch city of Woerden, built on a square plan with four corner towers and a water-filled moat running around the full perimeter. It is listed as a Rijksmonument, meaning it is protected as a national heritage site.
The castle was built in the early 15th century on the orders of Duke John of Bavaria to defend the border between Holland and Utrecht. In 1672, during the French occupation of the Netherlands, it was heavily damaged and later rebuilt.
The castle bridges its military past with its current role as a venue where historic walls now host guests for celebrations and conferences. The transformation shows how this location has maintained its importance across the centuries.
The castle sits in the heart of Woerden and is easy to reach on foot from the town center. Walking along the moat gives a clear view of the towers and the water defenses from all sides.
After its rebuilding in the late 17th century, the castle was incorporated into the Old Dutch Water Line, a system of deliberately flooded land used to stop advancing armies. This defense strategy used water not just as a moat but as a controlled landscape across a wide area.
