The Opéra Bastille is a modern opera house in the 12th arrondissement of Paris, France. Inaugurated in 1989 as part of President François Mitterrand's Grands Travaux, it became the main facility of the Paris National Opera, France's principal opera company, alongside the older Palais Garnier; most opera performances are shown at the Bastille along with some ballet performances and symphony concerts, while Palais Garnier presents a mix of opera and ballet performances.
Designed by Uruguayan architect Carlos Ott, it is located on Place de la Bastille. It may seat 2,723 people in total, with a main theatre, concert hall and studio theatre.
