The Crane (Żuraw) is one of the defining symbols of Gdańsk and represents what little is left of the city’s great trading age. First mentioned in 1367, the original structure was burnt down in 1442 before its current design was created in 1442-1444. As a working crane it was used to transfer cargoes and to put up masts on ships. At one time this was the biggest working crane in the world but it also served a defence function and as one of the gates to the city. It had a lifting capacity of 4 tonnes to a height of 11 metres and this was achieved by two huge wooden wheels at its heart each with a diameter of 6 metres. These wheels were originally powered by men walking inside of them to turn the lifting mechanism. It remained a working crane until the middle of the 19th century and was 80% destroyed in 1945 in the battle for Gdańsk.
After the war it was rebuilt and donated to the Polish Maritime Museum of which it remains a part today. You will be able to view a collection of permanent and temporary exhibitions inside including an exhibition on port life between the 16th and 18th centuries. In Polish only, displays include models of lighthouses, the old port, lifesize recreations of counting houses and old port life in general plus access to the crane's two huge drive-wheels.References:
Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
