Underneath the Petite Ceinture railway line, the cinema lobby is “enhanced”: as a new extension to the public highway, it is merged with one of the screening rooms to host various events. This versatile and vibrant space, regularly made available to local associations and institutions, is becoming a neighborhood agora for Porte d’Auteuil. At ground level, an art garden, run in part by Agripolis with an aeroponic growing system which is open to local residents, is home to a commissioned work of art.
