With its impressive height of 72 metres, Vienna’s first "real" office high-rise – the headquarters of Wiener Städtische Versicherung – was inaugurated in 1955, the year of signing the Austrian State Treaty, at the juncture of Ringstrasse and Danube Canal. Architecturally, too, this building exemplifies modern office design of the 1950s and the era of post-war recovery.
