ZURICH.- For more than forty years, the photographer couple Bernd (1931-2007 and Hilla Becher (*1934) worked on creating an inventory of industrial architecture. Warehouses, shaft towers, gas tanks, blast furnaces as well as half-timbered houses are among the subjects they photographed throughout Germany, England, France, Central Europe, and the USA. Calling these buildings “anonymous sculptures,” they refer to the artistic quality of the constructions, which played no role for the buildings’ largely unknown builders and users. Their photographs attempt to draw attention to these hidden sculptural qualities and to document them historically as a building tradition in decline. Bernd and Hilla Becher have always held particular interest for the industrial architecture in the Ruhr region. The exhibition Mines and Mills – Industrial Landscapes
