The National Maritime Museum (Polish: Narodowe Muzeum Morskie w Gdańsku) is located in Gdańsk at 9 - 13 Ołowianka Street. The aim of the museum is to collect and protect monuments related to shipping, boatbuilding, shipbuilding and fishing, and to disseminate knowledge about them, as well as about the maritime history of Poland and its economy. The museum has a number of divisions in Gdańsk. They are Granaries on Ołowianka island, S.S. Sołdek (first ship build in Poland after WWII), Żuraw (15th century wooden port crane), Maritime Culture Centre, Dar Pomorza (1909 Sailing Ship), Fisheries Museum, The Vistula River Museum and The Vistula Lagoon Museum. The Graneries on Ołowianka, being the main seat of the museum, are the most often visited. The exhibition here is set up on four floors of historic granaries accessible by ferry from Żuraw.
