Kasteel Radboud in Medemblik

You're standing at Radboud Castle, on the east side of the harbour in Medemblik. Take a look at the walls and towers. You'll see two residential wings, two square towers and one round corner tower. That's only part of the original castle. It once had roughly the same layout as Muiderslot castle. The rest disappeared over the centuries, but you can still make out its outline on the ground.
