Austria Center Vienna hosts international congresses, trade fairs, product presentations, galas and large company meetings, from about 500 guests up to 23,122 people for non-public events, or 21,162 for public ones. Opened in 1987 in Vienna, it is Austria's largest congress center, with 21 halls and 134 meeting rooms spread over five levels.
Seminars and company events
The venue is built for scale. Plenary sessions, all-hands meetings and product launches use the large halls, while more than 30 workshop rooms of up to 200 m² take breakout sessions in parallel. The sales team also handles corporate events, Christmas parties, galas with cocktail receptions and seated dinners, terrace settings and e-sports events. Branding can run across LED surfaces, including the polySTAGE installation in the entrance hall and 183 m² of LED areas on level -2. Audiovisual production, live streaming and studio setups for hybrid sessions are available on site.
The center was the first in Austria to be recognized as a Green Conference Center, and it offers Green Meeting certification under the Austrian Ecolabel at no extra cost. Regional sourcing for catering is part of that approach.
Rooms and capacities
The building offers 21 halls, 134 meeting rooms and five exhibition halls, X1 to X5, which together cover about 26,000 m². The largest hall, Saal ABC, takes more than 4,300 people for a plenary. Level -2 alone holds seven halls, 24 meeting rooms, three exhibition halls and two terraces, with daylight in its modern spaces. Level 0 adds four halls, 24 meeting rooms, two exhibition halls, the Business Lounge and the MOTTO Café. Three outdoor terraces in total serve breaks and receptions.
Accommodation
There are no bedrooms in the building. The center counts about 422 hotels in Vienna, several of them within walking distance, and its website helps delegates choose one.
Catering
Food and drink come from an exclusive catering partner, from coffee breaks to gala dinners for several thousand guests. Menus and service formats are set with the partner during planning.
History and setting
The center is run by IAKW-AG, a company owned by the Republic of Austria and founded in 1971 to build and manage the Vienna International Centre, which was handed over to the United Nations in 1979. Austria Center Vienna opened in 1987 after about four years of construction. It is the only congress center in the world directly connected to a UN headquarters, which supports high security standards. The EADV congress drew more than 20,300 attendees here in 2026.
Getting there
The venue sits in Vienna's 22nd district, a few minutes on foot from Kaisermühlen-VIC station on the U1 subway line. Stephansplatz in the historic center is seven minutes away by U1, Praterstern about 10 minutes and Vienna Hauptbahnhof about 20 minutes, all without changing trains. From Vienna International Airport, a taxi takes about 25 minutes and the airport express bus about 30 minutes.
