An orange-glowing staircase and 6,000 exhibits in a spectacular industrial setting: The Ruhr Museum's permanent exhibition at the Zollverein UNESCO World Heritage Site shows the fascinating natural and cultural history of one of the world's largest industrial regions. In its permanent exhibition, the regional museum of the Ruhr region shows the entire natural and cultural history of the region from the formation of coal more than 300 million years ago to today's structural transformation into the Ruhr metropolis. Visitors follow the former path of the coal and descend deeper and deeper from the present into the history of the region. Over three levels, they pass through windowless bunkers, huge industrial machines, raw concrete walls and conveyor belts. In between, 6,000 exhibits show in often fascinating detail how a formerly agricultural region developed into Europe's largest coal and steel production area and then became the Metropole Ruhr.
