Internationales Maritimes Museum Hamburg

In the page's words:

Hamburg is the gateway to the world and the route through three millennia of maritime history leads via the International Maritime Museum. At a historic site in the heart of the Free and Hanseatic City of Hamburg, in the traditional, beautifully restored Kaispeicher B, the sea comes to life - and everything that goes with it. On nine floors, appropriately called decks, and 12,000 square meters, the great freedom of the water, the development of shipping and the emergence of global trade routes are within reach.
