Schokland was formerly an island in the Netherlands but lost its island status over several stages in the 19th century. It is now a UNESCO World Heritage site located within a reclaimed polder due to its exceptional cultural and natural value representing the struggle against rising sea levels. The last remaining inhabitants were evacuated in 1859 by royal decree after repeated flood disasters made living on the island too dangerous. Schokland provides insight into the history and culture of the Netherlands through its preserved remnants of former villages and landscape within the Noordoostpolder.
