Duisburg is the westernmost city in the Ruhr district. It became an important industrial city in the 19th century, when the beginning of industrialization saw an emergence of coal mining and the steel industry. Duisburg is still the leading steel city in Europe today.
The university city is particularly famous for nanoscience and biomedical research and attracts innovative businesses to settle the Ruhr region. Duisburg Port is Europe's largest inland port and is of global significance. Located on the confluence of the Ruhr and the Rhein, it is both a logistics hub and tourist attraction at the same time.
