The Sydney Opera House is Australia's most recognisable building and  an icon of Australia's creativity. The facility features a modern  design  with a series of large spheres that mesure 75.2 metres. These spheres form the roofs of the structure. The building covers 4.4 acres of land and is 600 ft long and 394 ft wide. Several showings include, "Pennsylvaia Avenue," "Tiny Ruins,"  and "Vitesste," an Australian ballet. Tours the site are available in more then 7 languages. There are different packages, but most tours consist of a showing at the theater, luch, and a tour of the site. For the best experience, we recommend The Backstage Tour - Vivid live.
