The bunkerization of Europe is a Cold War story that has continued to resonate into the 21st century through foreign policy, the built environment, and cultural traces both material and imaginary. This essay explores the physical, ideological, and cultural bunkerization of Switzerland, one of the most heavily fortified countries in the world, through its military and civil defense history, the spatial manifestations of that history, and the cultural responses to these manifestations during and after the Cold War. The essay compares the unusually democratic process of the Swiss civil defense infrastructure and its ramifications for thinking about the spatial legacy of the Cold War with the bunker fantasy in the United States and the rest of Europe.
