With the majority of the Netherlands at or below sea level, the Dutch have battled the seas for centuries.
Along the Dutch coast, systems of dykes and barriers have been built, some of which have been in place for centuries.
One of the most ambitious of these - the Zuiderzee works - was built in the early 20th century.
In the wake of devastating flooding in 1916, the Dutch government decided to close off the Zuiderzee sea with a system of dams and dikes, land reclamation and water drainage work, creating instead an inland sea.
