73,000 m² of state-of-the-art infrastructure in the heart of Vienna: VIECON - Vienna Congress and Convention Center is Austria’s largest and most flexible venue for conferences, trade shows, and business events, accommodating 1,000 to 29,000 attendees. Four multifunctional halls totaling 55,000 m² and an adjacent Congress Center spanning approximately 7,000 m² offer maximum flexibility in event planning. Movable partition walls enable customized room layouts; the glass-enclosed mall connects the halls and the congress area, allowing for combined or concurrent events. An architectural highlight is the column-free Hall D, with 9,000 m² of floor space. It is ideal for large-scale setups, stage constructions, and flexible event designs. The venue is fully accessible, air-conditioned, and equipped with high-performance IT infrastructure. Short distances, clear logistics, and an experienced team create reliable conditions for professional execution. Centrally located with two subway stations directly on-site, the city center is just a few minutes away, and the airport is about 30 minutes away. Hotels, restaurants, universities, and the Vienna Prater are located in the immediate vicinity. VIECON holds two Austrian Ecolabels: it is certified as a Green Venue and facilitates the licensing of Green Meetings and Green Events. A dedicated sustainability manager supports event organizers in implementing responsible concepts. With an international focus and a part of Wien Holding - owned by the City of Vienna - since 2025, VIECON stands for stability, sustainability, and impactful events.
