The Province of Noord-Holland
The yacht harbour near the Muiderslot, a castle at the mouth of the river Vecht, about 15 kilometres southeast of Amsterdam, in Muiden, where it flows into what used to be the Zuiderzee. The castle was built in 1370 on the site of a previous castle, built about 100 years earlier.
