It is the headquarters of the federation of nonprofit mutual insurers of the Île-de-Francerégion, which rents its halls and rooms to outside users. The conference center has an attached restaurant.
La Mutualité hosts a variety of events, from the yearly meeting of the shareholders of small companies to important meetings of national political parties. Because of the latter, it often appears in the news.
French anarchist singer-songwriters Léo Ferré (see live album Léo Ferré Mai 68) and Renaud sang here. Congolese band Zaïko Langa Langa headlined many concerts in the hall between 1989 and 1991.
