The place seems to have many names; As Wikipedia explains it: “The Palais Garnier 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 is also often referred to as the Opéra Garnier.” And ummm… also known as: the Opera National de Paris.
