Pavillon Baltard, Historic monument and performance hall in Nogent-sur-Marne, France

Pavillon Baltard is a glass and iron structure with arched windows, high ceilings, and detailed metalwork displaying industrial architecture throughout. The space can accommodate between 500 and 2500 people for concerts, exhibitions, conferences, and private events.

The building was constructed in Paris during the 1850s by architect Victor Baltard and relocated to Nogent-sur-Marne in 1974. It remains the sole surviving structure from Baltard's designs for Les Halles, Paris's former central market.

The hall holds the Christie organ built in 1930 for the Gaumont Palace, then Europe's largest cinema. Classified as a historic monument on 28 March 1977, it was last played in 2003 and has not been maintained for years; the Association pour la valorisation et le rayonnement de l'orgue Christie, formed in late 2010, campaigns for its restoration.

The hall stands at 12 rue Victor-Hugo, with a second frontage on rue Victor-Basch in the Beauté-Baltard district. It is an event venue rather than a permanent museum, so access depends on the programme of concerts, fairs and television recordings held inside. The original iron grilles of the Paris Halles surround the building, and a Morris column and Wallace fountain stand nearby.

The pavilion is surrounded by the original iron railings of the Paris Halles, and nearby stand a Morris column and a Wallace fountain. A section of the Eiffel Tower staircase was once displayed outside; it has since been sold. A scene set in the Halles of Paris in Jean-Pierre Jeunet's film A Very Long Engagement was shot inside the pavilion.
