Origin and history

The Caisse d'allocations familiales de Paris, located in the 15th arrondissement, is a project created in 1946 when the central family allowance fund was established. The aim was to consolidate the services dispersed in various professional bodies in one place. This ambitious project was entrusted to architects Marcel Reby and Raymond Lopez, marking the beginning of a major achievement for the French social administration.

The work, begun in 1955, was completed in March 1959. The architectural complex consists of an eight-storey tower, called the Lopez Tower, and two low buildings dedicated respectively to directions, social services, and technical services. The structure is based on an innovative metal frame for the era, while the curtain facades, suspended by patellas with bank beams, represent a notable technical feat. These facades, composed of aluminium presseries and polyester panels, illustrate the architectural daring of this period.

Despite initial heritage recognition, with the inclusion of the Lopez Tower in the inventory of Historic Monuments by order of 9 November 1998, this protection was annulled by a judgment of the Administrative Court on 30 June 1999. The site, which is owned by a public institution, remains a significant testament to modern administrative architecture and its integration into the Parisian urban landscape.

The precise address of the monument, 10-26 rue Viala, 5bis-11 rue Saint-Charles and 36-44 rue du Docteur-Finlay, highlights its anchor in the neighborhood. The location, noted as fair (5/10) in the databases, reflects the mapping challenges for large urban complexes. This building embodies both an essential social function and a pioneering architectural experience for its time.
