The first day we will visit Bochum. Bochum is a industrial town in North Rhine-Westphalia with a population of nearly 365.000. Bochum became famous during the 19th century when coal and steel industries were emerging in the Ruhr area. After the 50's the coal and steel industries became less important and Bochum turned into an automotive city, where currently the Opel Astra is produced. In Bochum we will visit an automotive center of Brunel.
