Opera house

An opera house is a theatre building used for opera performances that consists of a stage, an orchestra pit, audience seating, and backstage facilities for costumes and set building. While some venues are constructed specifically for operas, other opera houses are part of larger performing arts centers.

The first public opera house came into existence in 1637 as the Teatro San Cassiano in Venice, Italy, in a country where opera has been popular through the centuries among ordinary people as well as wealthy patrons; it still has a large number of working opera houses. In contrast, there was no opera house in London when Henry Purcell was composing and the first opera house in Germany was built in Hamburg in 1678. Early United States opera houses served a variety of functions in towns and cities, hosting community dances, fairs, plays, and vaudeville shows as well as operas and other musical events.

In the 17th and 18th centuries, opera houses were often financed by rulers, nobles, and wealthy people who used patronage of the arts to endorse their political ambitions and social positions or prestige. With the rise of bourgeois and capitalist social forms in the 19th century, European culture moved away from its patronage system to a publicly supported system. In the 2000s, most opera and theatre companies raise funds from a combination of government and institutional grants, ticket sales, and private donations.

The Teatro San Carlo in Naples introduces the plant horseshoe, the oldest in the world, a model for the Italian theater. On this model were built following theaters of Italy and Europe, among others, the court theater of the Palace of Caserta, who will become the model for other theaters. Given the popularity of opera in 18th and 19th century Europe, opera houses are usually large, with generally more than 1,000 seats and often several thousand. Traditionally, Europe's major opera houses built in the 19th century contained between about 1,500 to 3,000 seats, examples being Brussels' La Monnaie (after renovations, with 1,700 seats), Odessa Opera and Ballet Theater (with 1,636), Warsaw's Grand Theatre (the main auditorium with 1,841), Paris' Opéra Garnier (with 2,200), the Royal Opera House in London (with 2,268) and the Vienna State Opera (the new auditorium with reduced capacity of 2,280). Modern opera houses of the twentieth century such as New York's Metropolitan Opera (with 3,800) and the San Francisco Opera (with 3,146) are larger. Many operas are better suited to being presented in smaller theatres, such as Venice's La Fenice with about 1,000 seats.
