The Hook of Holland area was created as a sandbar in the Meuse estuary, when it became more and more silted after St. Elizabeth's flood of 1421. All kinds of plans were designed to improve the shipping channel to Rotterdam. In 1863 it was finally decided to construct the New Waterway which was dug between 1866 and 1868. The route ran through the Hook of Holland, where a primitive settlement, Old Hook (Oude Hoek - nowadays the Zuidelijk Strandcentrum), was created. Many workers and senior employees of the Rijkswaterstaat settled in Old Hook.
