The main part of the museum is located inside three Renaissance granaries and if you've only got time to visit one of the three museums this is by far the most comprehensive of the lot. A complete history of Poland's nautical history is represented on several floors and includes old cannons, huge oil paintings, harpoon guns, a hall dedicated to underwater archaeology, shipbuilders' hard hats from the Lenin shipyard, a few pieces of modern art and an extensive collection of model ships. Information is available in English.

Admission 8/5zł. Guide tours up to 30 people 35zł, over 30 people 55zł.
