Few days before I have visited the Rhine River which is located on the historic French and German border crossing with my friend sadik. The “Cour des Douanes” in Strasbourg and the “Zollhofareal” in Kehl are former customs posts located on the historic French and German border crossing, along the Rhine River. Europe has opened up, customs post have shrunk, a once backyard territory is now open for future developments. It becomes possible to define the terms of a new relation between the two cities, to imagine a European transborder metropolis along the Rhine.
