Previously, previously, previously.
Many buildings in Chartres are lit up at night with elaborate animated patterns during the spring/summer. Well worth a side trip if you happen to be in northern France.
This old gas tank converted into a performance space sits alongside a canal in Oberhausen, Germany and right next to a little forest converted to a zipline adventurepark. It is in the middle of Germany's Ruhrgebiet region: a heavy industry center that has seen some decline. There are plenty of huge obsolete structures there. The local governments decided to preserve rather than tear them down. Also interesting are Zeche Zollverein (An old coal mine and kokarie) and Landschaftspark Duisburg (a steel mill).
The Duisberg-Essen-Dusseldorf is overlooked by most European visitors but contains some of that continent's most interesting 20th century relics. Skip Regensberg and go here instead.
