Duisburg

Duisburg (; , ) is a city in the Ruhr metropolitan area of the western German state of North Rhine-Westphalia. Lying on the confluence of the Rhine (Lower Rhine) and the Ruhr rivers in the center of the Rhine-Ruhr Region, Duisburg is the 5th largest city in North Rhine-Westphalia and the 15th-largest city in Germany.

In the Middle Ages, it was a city-state and a member of the Hanseatic League, and later became a major centre of the iron, steel, and chemicals industries. For this reason, it was heavily bombed in World War II. Today it boasts the world's largest inland port, with 21 docks and 40 kilometres of wharf. Provided by Wikipedia
