The Muiderslot is a castle in the Netherlands, located at the mouth of the river Vecht, some 15 kilometers southeast of Amsterdam, in Muiden, where it flows into what used to be the Zuiderzee. It's one of the better known castles in the Netherlands and has been featured in many television shows set in the Middle Ages.The Muiderslot is currently a national museum (Rijksmuseum). The insides of the castle, its rooms and kitchens, have been restored to look like they did in the 17th century and several of the rooms now house a good collection of arms and armour.
