Sydney Opera House

The Sydney Opera House is a multi-venue performing arts centre in Sydney, New South Wales, Australia, located on the foreshore of Sydney Harbour. It was designed by Jørn Utzon and completed in 1973 after a 16-year construction period, with significant cost and scheduling overruns. The building features a unique modern expressionist design with large precast concrete "shells" that form its roofs, and has become one of the world's most famous and distinctive buildings. It hosts over 1,500 performances annually and is visited by more than 8 million people each year, and has been recognized as a UNESCO World Heritage Site since 1998.learn more on wikipedia
