In Munich, the Olympic shopping centre is being built for the 1972 Summer Olympics. Many so-called guest workers were employed on the construction site. In 2016, nine people were murdered in a right-wing terrorist attack at this shopping mall. In 1982, Sohrab Shahid Saless made the film “Addressee Unknown“ in response to the rapid rise of racism in the Federal Republic of Germany. In this film, people repeatedly walk past walls and facades that are smeared with right-wing extremist slogans. By interweaving three historical eras, IN RETROSPECT impressively reveals the forces of hatred that also manifest themselves in architecture.
