UN City Vienna (Vienna International Centre): Tours & Tips

UNO City, officially known as the Vienna International Centre (VIC), opened in 1979 and is home to major United Nations institutions, including UNIDO (the UN Industrial Development Organization), the IAEA (International Atomic Energy Agency) and UNODC (the United Nations Office on Drugs and Crime). It is one of the four official UN headquarters worldwide – alongside New York, Geneva and Nairobi – and a symbol of Vienna's role as a bridge-builder in international diplomacy.

The modern architecture of the complex, designed by the Austrian architect Johann Staber, impresses with its hexagonal structure and futuristic appearance. The security measures around the site are a reminder of its importance. Visitors can access selected areas on organized guided tours and learn more about the work of the United Nations. The UN guided tour is especially popular, offering insights into conference rooms, artworks and the daily work of the organizations.

A worthwhile insider tip: right next door is Donau City with its modern high-rise architecture, as well as the Donaupark – ideal for a relaxing walk after your visit. Just a few minutes away on foot, the Danube Tower (Donauturm) tempts with its panoramic view. Multilingual tours are available for international guests, and the Viennese themselves also appreciate the chance to visit an institution of global political importance in their city.
