The iconic Sydney Opera House is arguably the city's most recognizable landmark. Its shell-like architecture is one of the first things that come to most people's minds when they think of Sydney. This UNESCO World Heritage Site is one of the most famous performing arts centers in the world. Sydney Opera House is made up of six smaller venues: Opera Theatre, Concert Hall, Drama Theatre, Playhouse, Studio, and the award-winning Guillaume Bennelong restaurant. A seventh space, The Forecourt, hosts free community events and large scale outdoor performances. People visit Sydney Opera House to enjoy the modern expressionist design of this unique architectural masterpiece, and to attend a performance by one of various companies, including the four key residential companies, Opera Australia, The Australian Ballet, Sydney Theatre Company, and Sydney Symphony.
