If you are looking for a reason to do a daytrip to Medemblik, this castle is partially worth the drive. The castle itself is really not reminiscent of the middle age, since it has been extensively rebuilt. The outside is nice for photo ops, so it's good for shutterbugs. There isn't a lot in the way of exhibits in the castle, and there are no placards in English. They do provide you with a three-ring binder with English information but it was much too unwieldly to lug around - a pamplet would have been easier. Across the way there is a small park with a cute little petting zoo which has goats, sheep and piggies. It was a nice way to spend an hour or so and if you couple a visit to the castle area as well as lunch in Medemblek followed by a short stroll around (especially if their little market is going on) it is a very nice daytrip.
