This project undertakes to design archives within one of the Flakturm, former Second World War anti-aircraft towers in the center of Vienna. The idea of constructing an archive within a bunker is not a neutral one. The defensiveness of this building allows, both symbolically and literally, to host and protect goods against the alteration of the externality —whether it is time or a more direct antagonism. Many civilizations of the past have been annihilated, not only physically, but absolutely as any form of their production has been also destroyed with them. The recent history would have still seen several tragic examples of ethnical cleansing directly linked to processes of cultural destructions.
