The Ruhr region in Germany is a collection of over ten cities in the state of North-Rhine Westphalen, and includes four major cities, namely Essen, Duisburg, Dortmund and Bochum. This region used to be the coal mining powerhouse of Germany till the first half of the 20th century. As a result, it still is Germany’s largest and most dense urban area with close to 5 million residents.
Traditionally, the Ruhr region has also been an industrial titan apart from its coal-based economy. Names such as Tengelmann Ventures, E.ON, Thyssen Krup, Aldi, and RWE hail from the Ruhr region. Even as a majority of the coal mines are now relics in the Ruhr region’s history and nature has taken over the pits that were abandoned, the Ruhr’s industrial base is fast becoming an enterprise startup hub.
