'Sydney, Australia - January 3, 2007: Front view of Sydney Opera House with a large group of tourists in a summer day in Sydney, Australia. The Opera House is a symbol of Australia. It has a unique, modern, expressionist design. One can see its interesting architectural features, such as the steep steps that lead to the Opera House entrance, as well as its glass windows and unique white roof that look like sails. The Opera House is located on the Circular Quay side of the Sydney Harbour.'
