The Keringhuis is the information centre for flood risk management in Zuid-Holland and the impressive Maeslant Storm Surge Barrier. The Dutch Delta Works are extremely important for the protection of our country against flooding, especially in the provinces Zeeland, Zuid-Holland and Noord-Brabant. The Delta Works construction is unique and therefore receives a lot of international attention. The Maeslant Storm Surge Barrier is the last part of the Delta Works. It is the largest movable flood barrier in the world. This impressive construction can’t be described in words, only experienced!
