One of Australia’s famous landmarks, the Sydney Opera House is one of the world’s most prestigious performing arts centers. Regarded as a 20th century architectural masterpiece, the Sydney Opera House was designed and built by architect, Jørn Utzon, to reflect the image of a huge sailing ship. Though the name suggests it is used only as an opera house, the project comprises multiple performance venues. Of the many venues housed within the structure, some of the most significant are the Joan Sutherland Theatre, Drama Theatre, the multi-purpose Utzon Room and the Concert Hall, which houses the largest mechanical tracker-action organ in the world. Also part of the Sydney Opera House is the Forecourt, an open-air venue presenting many outdoor performances.
