The Maison de la Mutualité is one of the few Paris venues that combines a true theatre with reception floors and meeting rooms under one roof, in a building whose Art Deco architecture has been carefully restored. Its location in the Latin Quarter, close to Notre-Dame and the universities, suits scientific meetings, political and association congresses as much as corporate conventions.
Conventions, general assemblies and conferences of several hundred to 1,725 participants in the theatre, association and scientific congresses that need breakout rooms, and gala dinners of up to 900 guests. The theatre seats can be cleared to free a floor of about 800 m², so the same room can host a plenary during the day and a reception in the evening, provided the turnaround time is planned.
Plenary sessions take place in the theatre, receptions and exhibitions in the Espace Maubert, and workshops or committee meetings in the nine Salons Rive Gauche on the fifth floor. The 90 m² TV studio allows sessions to be recorded or broadcast without installing a temporary set, a useful option for hybrid events.
For a larger plenary, compare the Palais des Congrès; for a monumental reception setting, the Palais Brongniart; and for a conference centre with two amphitheatres in the 7th arrondissement, the Maison de la Chimie. Evening capacities are compared in our guide to gala dinner venues.
