The Théâtre des Champs-Élysées () is an entertainment venue standing at 15 avenue Montaigne in Paris. It is situated near Avenue des Champs-Élysées, from which it takes its name. Its eponymous main hall may seat up to 1,905 people, while the smaller Comédie and Studio des Champs-Élysées above the latter may seat 601 and 230 people respectively. Commissioned by impresario Gabriel Astruc, the theatre was built from 1911 to 1913 upon the designs of brothers Auguste Perret and Gustave Perret following a scheme by Henry van de Velde, and became the first example of Art Deco architecture in the city. Less than two months after its inauguration, the Théâtre hosted the world premiere of the Ballets Russes' Rite of Spring, which provoked one of the most famous classical music riots. At present, the theatre shows about three staged opera productions a year, mostly baroque or chamber works more suited to the modest size of its stage and orchestra pit. It also houses an important concert season. It is the home venue of the Orchestre National de France and the Orchestre Lamoureux, and serves as a French base for the Vienna Philharmonic Orchestra as well. Architecture The theatre is built of reinforced concrete and features rectangular forms, straight lines, and decoration attached to the outside on plaques of marble and stucco, which was a radical departure from the Art Nouveau style, and, at the time, shockingly plain in appearance. The building's concrete construction was not merely a stylistic choice. Subsoil conditions and the site's proximity to the Seine made concrete necessary. Henry van de Velde was the initial architect, resigning when it was clear that the contractors, the Perret brothers, had a far deeper understanding of reinforced concrete construction than he did, although the Perrets, were not licensed architects and had another designer, Roger Bouvard, sign their plans. The building includes an exterior bas relief by Antoine Bourdelle, a dome by Maurice Denis, paintings by Édouard Vuillard and Jacqueline Marval, and a stage curtain by Ker-Xavier Roussel. The building houses two smaller stages, the Comédie des Champs-Élysées theatre on the 3rd floor, and the Studio des Champs-Élysées on the 5th floor. The building is considered a landmark of modern architecture, and has been a monument historique of France since 1957. Early history Gabriel Astruc was the first director of the theatre, and programmed contemporary music, dance and opera, including works by
