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.[1] 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.
