This attraction consists of an indoor museum (the Binnenmuseum) and an outdoor museum (the Buitenmuseum). The Binnenmuseum, whose main focus is the maritime activities of the region (fishing, navigation, commerce), occupies 12 buildings, including 17 C houses and warehouses that once belonged to the West India Company. The Buitenmuseum is a museum village devoted to daily life in the former fishing ports on the Zuiderzee (completion of the closing dyke).

The statue of the engineer Lely, designer from 1891 of the project to close off the Zuiderzee, crowns the side of Den Oever (entrance to the dyke). On the sea side, a breakwater protects a cycle track and a road. Below the dyke, on the IJsselmeer side, the fishermen spread their nets to catch eels. The Stevinsluizen (from the name of the engineer Stevin) forms the first group of locks (boat passage).

This elegant construction dates from 1613. Made from brick decorated with sandstone, it protected the port entrance. Its central part forms a bridge over the Geeuw and is flanked by two turrets which overlook the thin roofs. It is inset with arches.

Built in 1957, this water tower supplies potable water to all the polder and has a carillon with 48 bells. From the top, the view stretches all the way to the Friesian coast, Urk and the Flevoland-Is electric plant.
