Like few other places, Teufelsberg evokes fantasies and interest. The highest elevation in the city is intertwined with numerous facets of the city's history. Teufelsberg was part of the plans for the world capital Germania, and here lie the ruins of World War II. Later, after 1945, the Allies converted the area into a listening station. Today, it is the most prominent abandoned place in Berlin, a lost place. This ruinology dissects the layers of Teufelsberg and tells of the utopias and nightmares of the past. The history of Teufelsberg unfolds in this book as a metaphor for the city.
