Together with the director of the Museum Stadtgeschichtliches , Dr . Hans Brückner , took this idea from 1931 to more specific forms . With the knowledge of the museum specialist and the technical know - how of the port director , he founded one of the oldest collections on the history of navigation on the Rhine with graphic images , documents and ship models . This collection was originally presented to the public temporarily in 1936 during the Düsseldorf Harbor Festival at the State Museum , since 1937 the exposition has been permanently housed in the Green Refuge Planetarium in Erenhof . However , during the Second World War , the collection again lost its place and for a long time remained without a permanent exhibition building . It was available only at temporary exhibitions in different places . Despite the fact that in 1954 a large personal commitment was created between the Association of Friends and the sponsors to them . Heinrich Eterich to find a permanent exhibition area , the problem was solved only in 1978 . On March 28 , 1978 , the city council of Düsseldorf decided to place the Schiffahrt Museum in the castle tower . More than 2 million German marks were donated by companies and individuals for the restoration of the Schlosthurm and the opening of the Maritime Museum . After extensive restoration , the SchifffahrtMuseum at Schlossturm was opened in 1984 . The last complete reconstruction and redesign of the Maritime Museum took place in 2014 / 15 . From June 6 , 2015 , the museum is open again to visitors with restored ship models of the 1930s , recently purchased or donated exhibits and numerous regular loans from famous museums in Germany .
