The Sydney Opera House turns 50

A building to inspire

A series of shells, the billow of sails, the crests of foaming waves – the Sydney Opera House’s silhouette is globally recognised. Together with the Sydney Harbour Bridge, it’s a sight that defines Sydney.

The most famous couple in Sydney. The Sydney Opera and the Sydney Harbour Bridge are the globally recognised symbols of our harbour city - you can't have one without the other.

The vision of a genius

Jan Utzon’s design was not well-developed when it was picked as the basis for the new Sydney Opera House. But with its dramatic, peeling shell segments, it was the standout concept. It captured the judging panel’s imagination, trumping more conventional designs.

Engineers, architects and builders had to solve many challenges to make Utzon's design a reality. The roof alone took 5 years to perfect. Segments constructed in precast concrete and assembled onsite with specially designed cranes. In total, construction took 14 years!

Location, location, location

It’s hard to imagine the harbour foreshore without the Sydney Opera House. But Bennelong Point / Dubbagullee was not always the preferred site. More than 30 locations were considered, including converting the Queen Victoria Building. Other possible locations were opposite Hyde Park, The Domain between the Art Gallery of NSW and St Mary’s Cathedral. Even the Royal Agricultural Grounds at Moore Park were an option.

At the time, the Hilton Hotel was putting pressure on the City to redevelop the QVB site into a hotel!

A very crowded house

Some of Sydney’s most memorable social and cultural moments have played out on the steps and forecourt of the Sydney Opera House. The ‘house for the people of Sydney’ has seen concerts , art installations, protests, Olympic events and millions of selfies. In 1997, tens of thousands of people came to see Crowded House play, free.

A canvas

The sails of the Sydney Opera House are a canvas on which both human and natural light play. Projection on the sails during Vivid Sydney delights millions of people every year. But the way the 1,056,006 tiles reflect the changing light throughout the seasons is arguably much more beautiful.
