Over the course of nearly five decades, Bernd and Hilla Becher documented almost every type of industrial architecture—from water towers and steel mills to gas tanks and grain silos—in Europe and the United States. Whether presenting single shots or their signature typological grids, the Bechers created a photographic testament to the industrial revolution that so emphatically shaped the nineteenth and twentieth centuries. At the same time, however, they also captured a much older manufacturing tradition: the quarrying and processing of stone. This volume, an essential addition to the Bechers' ouevre, is devoted to their photographs of rock-processing plants and lime kilns taken in Germany, France, The Netherlands, Belgium, Switzerland, Austria and Great Britain throughout the 1980s and 90s. Each structure is unique, its details dependent upon the region and the date of its construction, and the book features buildings whose essential function is ancient but which remain important today.
