The Palais Garnier, known also as the Opéra de Paris or Opéra Garnier, but more commonly as the Paris Opéra, is a 1,600-seat opera house on the Place de l'Opéra in Paris, France, which was the primary home of the Paris Opera from 1875 until 1989. A grand building designed by Charles Garnier in the Neo-Baroque (or "Baroque Revival") style (it is also said to be of the related Second Empire style), it is regarded as one of the architectural masterpieces of its time.
The building is located in the 9th arrondissement of Paris and is served by the metro station Opéra and bus 21, 22, 27, 29, 42, 53, 66, 68, 81, 95.
Upon its inauguration during 1875, the opera house was named officially the Académie Nationale de Musique - Théâtre de l'Opéra. It retained this title until 1978 when it was re-named the Théâtre National de l'Opéra de Paris. After the opera company chose the Opéra Bastille as their principal theatre upon its completion during 1989, the theatre was re-named as the Palais Garnier, though Académie Nationale de Musique is still sprawled above the columns of its front façade. In spite of the change of names and the Opera company's relocation to the Opéra Bastille, the Palais Garnier is still known by many people as the Paris Opéra, as have all of the several theatres which have served as the principal venues of the Parisian Opera and Ballet since its initiation.
