The Crane over the Motlawa River is the most characteristic and unmistaken symbol of Gdańsk. Back in the Middle Ages it was the largest port crane in Europe handling cargo and putting up ship masts. It also served as an uncommon city gate. The reconstructed driving mechanism inside, still in working condition, is an immense wooden wheel originally propelled by men literally walking in it. Today the majestic Crane, a fine specimen of the historic port facilities, sets an excellent background for the rich collection of the National Maritime Museum.
