Gdańsk's National Maritime Museum is made up of four individual museums, including The Crane and the Sołdek ship (closed for refitting at the moment), that together create a complete history of the port. Straddling both banks of the Motława, tickets are bought individually to each part plus you need to buy a ticket on the ferry which sails between the Crane and the museum on the opposite bank. Tickets for the ferry cost 1.50zł each way and it offers a handy shortcut for those looking to get to the other side of the river even if you're not visiting the museum
