The iconic building on Sydney Harbour, Sydney Opera House, has joined other famous world structures such as India's Taj Mahal and the Great Wall of China when it was inscribed a World Heritage Building by the United Nations Education, Scientific and Cultural Organisation's World Heritage Committee on June 28, 2007.
Sydney Opera House was described by the UNESCO committee as a "daring and visionary experiment that has had an enduring influence on the emergent architecture of the late 20th-century. The building is a great artistic monument and an icon."
Sydney's iconic symbol
Sydney Opera House joined 16 other Australian World Heritage sites at the time. Australia's World Heritage sites have now increased to 19.
Designed by Danish architect Joern Utzon, who won a worldwide competition to design Australia's national opera house, Sydney Opera House was officially opened by Queen Elizabeth II on October 20, 1973.
It has since become identified so closely with Sydney it has become an undisputed symbol of the harbour city.
4.5 million visitors yearly
An estimated 4.5 million people visit Sydney Opera House every year. Of these, 1.5 million attend a performance at Sydney Opera House.
It seems no visitor to Sydney has failed to ride or walk to Bennelong Point where Sydney Opera House gleams whitely against the Sydney sky, its feet washed by the waters of the harbour.
