Opened within the Paris Expo Porte de Versailles exhibition park, the Paris Convention Centre gives Paris a plenary room of 5,200 seats, the largest in the city, with conference rooms and exhibition space stacked over four levels around a naturally lit atrium that looks out over the Paris skyline. Its scale is its strength, and it is also the first thing to plan for.
International congresses of 3,000 to 5,200 delegates in plenary, and events that combine a congress with a large exhibition, since the rest of the park offers 169,400 m² of pavilions next door. Below a few hundred attendees the building feels oversized and its distances work against the programme; a more compact venue will serve such an audience better.
Delegates reach the congress centre through the exhibition park, and the walk from the park entrances and the tram and metro stops takes several minutes. Signage from every entrance to the congress levels, and welcome staff at the main decision points, matter as much as the plenary itself, especially on the opening morning when thousands of badges must be collected in a short window.
Delivery vehicles reach the congress centre through the exhibition park, which runs its own logistics rules, so ask the venue early how vehicles are admitted (passes, access badges, time slots) and register your suppliers well before load-in. Confirm the delivery procedure, the maximum vehicle size and the lift capacity to the level you are using as soon as the contract is signed, and plan an installation window of at least one and a half times your team's estimate.
For a plenary of up to 3,700 seats with more than a hundred breakout rooms at Porte Maillot, compare the Palais des Congrès de Paris, or read our side-by-side comparison of the two congress centres.
