The Zenger Transformer Station stands on an exposed site in Malá Strana. Although its story dates back almost a hundred years and features important actors in interwar Czechoslovakia, the building’s significance has remained hidden for a long time. The book The Zenger Transformer Station: Electricity in the City, Electricity in Architecture not only presents the industrial building itself but also, against the background of its complicated origins, represents a layered investigation into the period when modern Prague was being forged.
