History of UNO City

The concept for establishing an international organization in Vienna was initiated by Chancellor Dr. Bruno Kreisky. This led to the construction of the Vienna International Centre, known as UNO City, designed by Austrian architect Johann Staber, between 1973 and 1979. Upon its completion in 1979, UNO City officially became a major United Nations site in Vienna, housing various international organizations and approximately 5,000 employees. It solidified its status as one of the four principal UN headquarters worldwide, reflecting its **enduring global importance**. The complex later underwent significant renovations, including asbestos removal and the construction of the new M Building from 2000 to 2009.
