The Maritime Museum Harbour contains a collection of historic vessels and cranes which are maintained in working condition.

The Maritime Museum includes both permanent and changing exhibitions designed for three generations: children, their parents and grandparents.

Furthermore, it includes the pen-and-ink drawings of Willem van de Velde and sea charts of the Corpus Christi collection by the master cartographer Joan Blaeu.

This is a collection of East India Company charts that lay hidden in England for three hundred years and came to the Maritime Museum in 2006 after being purchased for millions.

The Maritime Museum Harbour includes the red cast iron Low Light of the Hook of Holland, which formerly stood at the entrance to the Nieuwe Waterweg (New Waterway).
