Kasteel Radboud
A thirteenth-century brick castle on the Medemblik harbour, built by a count to hold down the Frisians.
Updated 21 October 2026
Floris V, Count of Holland, built a ring of castles across West Friesland after subduing the region in 1282, and Radboud at Medemblik is the one that survives - a square brick castle with round corner towers and a moat, on the harbour, put up not to defend the Frisians but to control them, which the local population understood and resented. It was reduced over the centuries and only part of the original plan stands; what is left was restored heavily in the 1890s by Pierre Cuypers, the architect of the Rijksmuseum, in a manner that added as much as it preserved. Inside is a knights' hall and an exhibition on Floris and the castle ring. Medemblik around it is one of the oldest towns in the province, a working harbour on the IJsselmeer with a marina, and the terminus of the museum steam railway from Hoorn.
