At former coal mine Zollverein in Essen, Germany, there is, placed in the former coal washery, a museum showing the history of Ruhr area, for more than hundred years the largest coal mining area in Europe. The pano shows the entry level of this "Portal of Industrial Hertitage". The complete mining area "Zollverein" was created by visional architects Schupp and Kremmer, who designed the buildings strictly symmetrical.
Located along the river Ruhr, Essen was traditionally a significant coal and steel center, one of the largest in Germany. Essen has modernized, hosting a number of large German corporations and boasting a vibrant cultural offering at a number of venues, particularly the Aalto Theater, which is an architectural masterpiece and home to ballet and opera. Essen is also regarded to be a “city of shopping”, particularly since the opening of the Metropolis shopping mall.
