Bjorn's sister Julia took us along with her and her friends this evening to a series of events celebrating the industrial history of the Ruhrgebeit. This was done using lights, displays, art and shows, and allowed us to see how lesser known German cities such as Bochum and Duisberg have existed and made their name for the last number of years. Got to walk through a mining museum set beneath the head frame of an old mine, as well as watching a dance and bmx show set to lights and music. Fun night!
