On Sydney Harbour.

The Sydney Opera House is a multi-venue performing arts centre in Sydney, New South Wales, Australia. Situated on Bennelong Point in Sydney Harbour, close to the Sydney Harbour Bridge, the facility is adjacent to the Sydney central business district and the Royal Botanic Gardens, between Sydney and Farm Coves.

Designed by Danish architect Jørn Utzon, the facility formally opened on 20 October 1973, by Queen Elizabeth II, with members of the British Royal family in attendance after a gestation beginning with Utzon's 1957 selection as winner of an international design competition. The Government of New South Wales, led by the 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.

Identified as one of the 20th century's most distinctive buildings and one of the most famous performing arts centres in the world, the facility is managed by the Sydney Opera House Trust, under the auspices of the New South Wales Ministry of the Arts. The Sydney Opera House became a UNESCO World Heritage Site on 28 June 2007.
