Who was the architect of the opera house where Thaïs was first performed?
Palais Garnier The Palais Garnier (] French    ) is a 1,979-seat opera house, which was built from 1861 to 1875 for the Paris Opera. It was 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 (French    ) and historically was known as the Opéra de Paris or simply the Opéra, as it was the primary home of the Paris Opera and its associated Paris Opera Ballet until 1989, when the Opéra Bastille opened at the Place de la Bastille. The Paris Opera now mainly uses the Palais Garnier for ballet.
Tivoli Theatre, Aberdeen The Tivoli Theatre, is a theatre in Aberdeen, Scotland, opened in 1872 as Her Majesty's Theatre and was built by the "Aberdeen Theatre and Opera House Company Ltd", under architects James Matthews of Aberdeen and C.B. Phipps, a London-based architect brought in to consult. The auditorium was rebuilt in 1897 by theatre architect Frank Matcham, but then closed temporarily in 1906, following the opening of the larger His Majesty's Theatre. The smaller theatre was extensively reconstructed in 1909, again by Frank Matcham, and re-opened in July 1910 as the Tivoli. The Tivoli was refurbished again in 1938.
