Why Buenos Aires
Buenos Aires is the number one city in the Americas for international association meetings: it hosted 91 events in the ICCA Ranking 2025 and ranked first on the continent for the 15th consecutive edition, according to the Buenos Aires City Tourism Board report. The full rankings are in Argentina meetings industry statistics. This page lists the large venues where those congresses, trade shows and events take place.

What to keep in mind
- The set-up defines the real capacity. A hall for 4,000 theatre style loses a lot of seats with a stage, side screens, interpreting booths or tables. Ask for the technical floor plan and the approved capacity for your layout.
- Mass events need their own permit. In the City of Buenos Aires, depending on audience size and event type, you need a specific permit, an evacuation plan and access control. We explain it in event permits in Buenos Aires: capacity and access control.
- Each venue has its own build-up rules. Build-up and tear-down times, floor loads, rigging points and approved suppliers change from one venue to another; read them before you quote the technical production.
- Accreditation and entry. With thousands of attendees, the bottleneck is the door. See how we handle it in QR accreditation for congresses.
- Book early. International congresses choose their host city years ahead, and the best dates at the large venues go first.
