Flevoland is a province of the Netherlands. Located in the centre of the country, at the location of the former Zuiderzee, the province was established on January 1, 1986; the twelfth province of the country, with Lelystad as its capital. The province has approximately 394.758 inhabitants and consists of 6 municipalities. After a flood in 1916, it was decided that the Zuiderzee, an inland sea within the Netherlands, would be enclosed and reclaimed: the Zuiderzee Works started. In 1932, the Afsluitdijk was completed, which closed off the sea completely.
The first part of the new lake that was reclaimed was the Noordoostpolder (Northeast polder). This new land included the former islands of Urk and Schokland and it was included in the province of Overijssel. After this, other parts were reclaimed: the Southeastern part in 1957 and the Southwestern part in 1968. There was an important change in these post-war projects from the earlier Noordoostpolder reclamation: a narrow body of water was preserved along the old coast to stabilise the water table and to prevent coastal towns from losing their access to the sea. Thus Flevopolder became an artificial island joined to the mainland by bridges.
The municipalities on the three parts voted to become a separate province, which happened in 1986. At Flevoland there is a large mediumwave broadcasting facility called Mediumwave transmitter Flevoland. Flevoland was named after Lacus Flevo, a name recorded in Roman sources for a large inland lake at the southern end of the later-formed Zuiderzee. Draining the Flevoland polders found many wrecks of aircraft that crashed into the IJsselmeer during World War II, and also fossils of Pleistocene mammals.
