In Dortmund graffiti has got the initial ignition for the Ruhr area and even today music plays there. Dortmund’s Union district is constantly changing and a walk down Adlerstraße can be quite exhausting. There’s nowhere to rest your eyes and when you almost start to squint, you reach Adler 59 – and that’s when it really gets going! You should pick up a mixed bag of sweets from the kiosk beforehand. Sugar is nerve food; you’ll need it now. Don't hesitate and follow me into the backyard.
