Zuiderzee Museum

The Zuiderzee Museum, located on Wierdijk in the historic center of Enkhuizen, is a Dutch museum devoted to preserving the cultural heritage and maritime history from the old Zuiderzee region. With the closing of the Afsluitdijk (Barrier Dam) on May 6th, 1932, the Zuiderzee was split in two parts: the waters below the Afsluitdijk are now called the IJsselmeer, while the waters north of it are called the Waddenzee.
