This little tower in Weiach from 1910 is one of the few remaining electricity substations in the Dielsdorf district. At the start of the 20th century, when Switzerland first got electricity, these types of buildings began to spring up. Their design is very varied, for example historicist brick constructions or the refined styles of Art Nouveau or Heimatstil. The building in Weiach has an undulating mansard pitched roof, a typical feature of Heimatstil harking back to preindustrial construction traditions. (image used with permission)
