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 on May 28, 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 now considered to be part of the Waddenzee.
