Flevopolder

About

The Flevopolder is an island polder in Flevoland, a province of the Netherlands. Created by land reclamation, its northeastern part was drained in 1955 and the remainder—the southwest—in 1968. Unlike other major polders, the Flevopolder is surrounded by lakes and below-sea-level channels. By some definitions, it is the world's largest artificial island.
