Hangar Y can host conventions, seminars, study days, product launches, gala dinners, trade shows and fashion shows, from 25 people in a workshop room to 1,600 in the main nave. The building stands at 9 avenue de Trivaux in Meudon, in the Hauts-de-Seine, 3.5 kilometers from the Porte de Sèvres, inside a park of 10 hectares.
Seminars and company events
The venue sells seminars, conventions, launches and custom events, and books spaces in whole or in part. The workshop, called L'Atelier, covers 311 square meters and takes 25 to 140 people for seminars, study days and training. It can be used as one large room or divided into four separate rooms with movable soundproof partitions, all in daylight. The adjoining restaurant, the foyer and an outdoor pontoon along the basin extend a meeting into lunch or a cocktail.
For larger plenaries, launches or galas, the nave takes 200 to 1,600 people. The venue also offers ready-made group activities, from a cultural rally for 200 or more to team challenges for 140 to 500, built around the history of the site.

History and setting
Hangar Y was built in 1879, reusing parts of a hall from the 1878 Paris Universal Exhibition, and is described as the world's first airship hangar. In August 1884 Charles Renard and Arthur Krebs flew the airship La France on the first closed-circuit flight from here. The Ministry of Culture bought the building in 1990, it was listed as a historic monument in 2000, and it reopened in spring 2023 after forty years closed and more than two years of work. The park and the basin surround the hangar.
