Salle du conservatoire, Concert hall in 9th arrondissement, Paris, France

The Salle du Conservatoire is a former symphonic concert hall in the 9th arrondissement of Paris, now part of the Conservatoire national supérieur d'art dramatique on rue du Conservatoire. Its horseshoe-shaped Italian theatre auditorium holds 956 seats, with 30 boxes of four to six seats on the parterre, a first balcony, 32 second boxes and four third boxes. The building's light grey and tan facade has three large white-framed windows crowned by carved round medallions, stepped gables on the left, and a street sign reading "SALLE COLEU".

The hall was ordered by imperial decree of 3 March 1806 and built by architect François-Joseph Delannoy for the exercises of the Conservatoire de musique et de déclamation, replacing a smaller hall at the corner of rue Bergère and faubourg Poissonnière. It opened on 7 July 1811. From 6 March 1828 it housed the Société des concerts du Conservatoire under François-Antoine Habeneck, who introduced Parisian audiences to Beethoven.

From 1828 the hall was home to the Société des concerts du Conservatoire under François-Antoine Habeneck, who introduced Parisian audiences to Beethoven's symphonies. Berlioz's Symphonie fantastique was premiered here in 1830, followed by Lélio (1832), Harold en Italie (1834) and Roméo et Juliette (1839). Since 2013 the ensemble Le Palais royal has been in residence, performing several times a year.

The hall sits within the CNSAD buildings on rue du Conservatoire in the 9th arrondissement. It is no longer suited to large symphonic concerts after its 1985 restoration, so it hosts only occasional performances, such as the Théâtre de la Ville shows and the Palais royal ensemble in residence since 2013. Check what is programmed before visiting.

The hall gained a reputation for its exceptional sound quality and earned the nickname 'Stradivarius of concert halls' among musicians. This acoustic advantage made it a sought-after venue during the 19th century where music could be heard in optimal conditions.
