If you only have time to visit one of the four branches of Gdańsk's Maritime Museum, make it this one - the main branch and most comprehensive of the lot, located inside three Renaissance granaries across the river from the Crane. 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.
