There’s no other barrier in the world which has larger movable parts than the Maeslantkering. This part of the Deltaworks can handle a tidal wave of 5 metres above average sea level.
The Maeslantkering can be found in the Nieuwe Waterweg near Hoek van Holland and was built between 1991 and 1997. The structure is fully automatically operated.This structure forms, together with the Hartelkering and the widening of the dykes at Rozenburg , the Europoortkering. The Maeslantkering is a primary barrier, which means that it deals with the tidal waves from the sea. Hereby protects the stormvloedkering the inhabitants of the province of Zuid-Holland.
