Brief synthesisThe Zollverein XII Coal Mine Industrial Complex is an important example of a European primary industry of great economic significance in the 19th and 20th centuries. Criterion (ii): The Zollverein XII Coal Mine Industrial Complex is an exceptional industrial monument by virtue of the fact that its buildings are outstanding examples of the application of the design concepts of the Modern Movement in architecture in a wholly industrial context. IntegrityThe Zollverein Coal Mine Industrial Complex in Essen comprises all the elements of intensive 19th and 20th century industrial exploitation – the complete complex of buildings and equipment necessary for the extraction and treatment of coal and the production of coke, the required transportation network (in the case of railways) as well as the vast heaps of pit waste. AuthenticityThe Zollverein XII Coal Mine Industrial Complex has a high level of authenticity. In particular, the authenticity of the important group of industrial buildings designed for Zollverein XII by Fritz Schupp has been carefully conserved.
