The Palais Garnier (pronounced: [palɛ ɡaʁnje]; English: Garnier Palace) is a 1,979-seat opera house, which was built from 1861 to 1875 for the Paris Opera. It was originally called the Salle des Capucines because of its location on the Boulevard des Capucines in the 9th arrondissement of Paris, but soon became known as the Palais Garnier in recognition of its opulence and its architect, Charles Garnier. The theatre was also often referred to as the Opéra Garnier, the Opéra de Paris or simply the Opéra. The Paris Opera now mainly uses the Palais Garnier for ballet.
