The Sydney Opera House is a multi-venue performing arts centre in Sydney, New South Wales, Australia. Designed by Danish architect Jørn Utzon, the facility formally opened on 20 October 1973 after a gestation beginning with Utzon’s 1957 selection as winner of an international design competition.

The Fort Macquarie Tram Depot, occupying the site at the time of these plans, was demolished in 1958 and construction began in March 1959. The Sydney Opera House was built in three stages: stage I (1959–1963) consisted of building the upper podium; stage II (1963–1967) the construction of the outer shells; stage III (1967–1973) interior design and construction.
