Situated on Bennelong Point in Sydney Harbour, close to the Sydney Harbour Bridge, the facility is adjacent to the Sydney central business district and theRoyal Botanic Gardens, between Sydney and Farm Coves. Designed by Danish architect J?rn 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 NSW Government, led by Premier Joseph Cahill authorised work to begin in 1958, with Utzon directing construction. The government"s decision to build Utzon"s design is often overshadowed by circumstances that followed, including cost and scheduling overruns as well as the architect"s ultimate resignation.
