Splinter goes back to the time of the last stadtholder Willem V, who was an avid collector. A large part of his collection of works of art and natural history objects was stolen by the French during the French period. Unfortunately, only part of it has been found. In the Naturalis natural history museum in Leiden, collection expert Steven van der Mije shows which animals, stuffed and in strong water, once belonged to the governor's collection. And Martine Gosselink, director of Mauritshuis, shows which beautiful paintings Willem V collected and how the Netherlands stole the paintings back.
