Queen Elizabeth II officially opened the Sydney Opera House on 20 October 1973, marking the end of 14 years of construction and the beginning of a new chapter for Australia’s cultural life.
Located at Bennelong Point in Sydney Harbour, the Sydney Opera House has become one of the world’s most recognisable architectural landmarks, attracting millions of visitors and hosting performances throughout the year.
A project that took 14 years to complete
Construction of the Sydney Opera House began in 1959, following Danish architect Jørn Utzon’s winning design in an international competition held in 1956.
The ambitious project faced technical challenges, delays and rising costs. Utzon left the project in 1966 following disagreements with the New South Wales government, and Australian architects completed the building.
Despite the difficulties, the finished structure became a landmark in modern architecture, recognised for its distinctive sail-shaped roof shells overlooking the harbour.

Queen Elizabeth II officially inaugurated the building on 20 October 1973, in a ceremony attended by dignitaries and members of the public.
The opening marked a significant moment for Australia’s cultural development, establishing a major venue for opera, music, theatre and other performing arts.
The building’s opening also brought international attention to Sydney, strengthening the city’s reputation as a cultural destination.
A global architectural icon
The Sydney Opera House has since become a defining symbol of Australia. Its performance venues host thousands of events, while its distinctive design makes it one of the country’s most photographed attractions.
In 2007, UNESCO added the Sydney Opera House to its World Heritage List, recognising its architectural significance and influence on modern design.
More than five decades after its inauguration, the landmark remains central to Sydney’s cultural identity and continues to welcome artists and audiences from around the world.
