Urk

Urk is first mentioned in historical records dating to the 10th century, when it was still an island in the Zuiderzee, an inland sea that would become part of the IJsselmeer in the 13th century after a series of incursions by the North Sea. In 1939, a dike from the mainland to Urk ended the town's island status, just as the Afsluitdijk project was changing the salt water Zuiderzee surrounding Urk to the less saline IJsselmeer. Later in the 20th century, seabed areas surrounding Urk were reclaimed from the sea to become the Noordoostpolder.
