Performers act inside a space shuttle decor during a rehearsal of Giacomo Puccini's La Boheme at the Opera Bastille in Paris, on April 26, 2023. - Opera Bastille is one of the largest opera houses in the world with a main stage of 750 square metres, which include side and back stages of similar dimensions, for a total space of 5000 square metres. Bastille also has an area identical to the main stage of 5000 square metres, 25 meters below the main stage. All these spaces make it possible to assemble, dismantle and store the sets of the different shows programmed simultaneously with a 400 square metre elevator capable of carrying up to 300 tons in 12 minutes from the underground staging area to the main stage.
