The Opéra de Monte-Carlo is an opera house, which is part of the Monte Carlo Casino located in the Principality of Monaco.
With the lack of cultural diversions available in Monaco in the 1870s, Prince Charles III, along with the Société des bains de mer, decided to include a concert hall as part of the casino. The main public entrance to the hall was from the casino, while Charles III's private entrance was on the western side. It opened in 1879 and became known as the Salle Garnier, after the architect Charles Garnier, who designed it.
During the renovation of the Salle Garnier in 2004–05, the company presented operas at the Salle des Princes in the local Grimaldi Forum, a modern conference and performance facility where Les Ballets de Monte Carlo and the Monte-Carlo Philharmonic Orchestra regularly perform.
The architect Charles Garnier also designed the Paris opera house now known as the Palais Garnier. The Salle Garnier is much smaller, seating 524, compared to about 2,000 for the Palais Garnier, and unlike the Paris theatre, which was started in 1861 and only completed in 1875, the Salle Garnier was constructed in only eight and a half months. Nevertheless, its ornate style was heavily influenced by that of the Palais Garnier, and many of the same artists worked on both theatres. Although the Monte Carlo theatre was not originally intended for opera, it was soon used frequently for that purpose and was remodeled in 1898–99 by Henri Schmit, primarily in the stage area, to make it more suitable for opera.
The hall was inaugurated on 25 January 1879 with a performance by Sarah Bernhardt dressed as a nymph. The first opera performed there was Robert Planquette's Le Chevalier Gaston on 8 February 1879, followed by three additional operas in the first season.
With the influence of the first director, Jules Cohen (who was instrumental in bringing Adelina Patti) and the fortunate combination of Raoul Gunsbourg, the new director from 1892, and Princess Alice, the opera-loving American wife of Charles III's successor, Albert I, the company was thrust onto the world's opera community stage. Gunsbourg remained for sixty years, overseeing such premiere productions as Hector Berlioz's La damnation de Faust in 1893, and the first appearances in January 1894 of the heroic Italian tenor Francesco Tamagno in Verdi's Otello, whose title role he had created for the opera's premiere in Italy. Conductor Arturo Vigna served as music director of the Monte Carlo Opera from 1895-1903.
