Hardly any architectural movement in Austria has been debated as controversially as Postmodernism. This article examines its genesis, manifestations, and reception at the intersection of international theory and the radical Aus-trian avant-garde tradition of the 1960s. The study illustrates how an independent formal language emerged from the rejection of functionalist dogma. This spectrum ranged from Hans Hollein’s symbolic small-scale architecture and his credo “Everything is Architecture” to the provocative, organic designs of Friedensreich Hundertwasser. While Rob Krier shaped urban planning concepts focused on reclaiming urban space, architects such as Wilhelm Holzbauer set postmodern accents in public educational buildings. The analysis clarifies that Austrian Postmod-ernism was not a mere import, but a productive synthesis of irony, monumentality, and local context—a unique architectural legacy that continues to significantly influence the country’s building culture today.
