The Esplanade des Invalides, a vestige of the 1900 World Fair, is owned by the City of Paris and the SNCF. It includes the Invalides old station, transformed in 1948 into a terminal and now managed by Air France, which hosts a RER C exit and a connection to lines 8 and 13 of the metro. The building of 3 800m ² includes three levels including one in the basement. Under the esplanade des Invalides, an huge underground space extends over 18 000m² between the Fabert street and the terminal. Developed with Emerige, Nexity and SemParisSeine, the Aerog'Art project will transform the vast infrastructure into a new architecture, open to the city through multiple new uses, while retaining as much as possible the heritage qualities of its existing architecture.

The project will include:

- An exhibition space dedicated to the art and crafts, with spaces of workshops and showrooms, in the volume of the old Invalides station.

-A children museum (6-12 years old) and a food market in the basement spaces.

-A courtyard of 1200m² along the building, as a public place, giving access to the RER and to the preserved restaurant "Chez Françoise".
