Hangar Y, the world's first airship hangar, was built in 1878 for the Universal Exhibition.
After decades of neglect, it has now been reborn as a major cultural venue in Greater Paris.
Urban Act, in collaboration with landscape architect Christian Fournet, orchestrated the rehabilitation of the site, highlighting the historic perspective designed by Le Nôtre and redeveloping the Bassin de Chalais park. The project has restored a cultural, ecological and landscape heritage, integrating soft paths, relaxation areas and artistic installations. This guided tour invites you to go behind the scenes of this transformation, to understand the architectural and landscaping choices made, and to appreciate how past and present intertwine to offer a unique place, open to all.
With Urban Act, a craftsman architecture and urban planning agency.
