The Sydney Opera House is one of the world's most recognizable and celebrated buildings, renowned for its unique sail-shaped roof design. Situated at Bennelong Point on Sydney Harbour, Australia, it was designed by Danish architect Jørn Utzon, who won an international competition in 1957. The building officially opened in 1973 after a challenging construction period marked by innovation, delays, and budget overruns. It is considered a masterpiece of 20th-century architecture and has become a symbol of both Sydney and modern Australia.
The Opera House features multiple performance spaces, including the famous Concert Hall and Joan Sutherland Theatre. It hosts over 1,800 performances annually, attracting millions of visitors from around the world. In 2007, it was designated as a UNESCO World Heritage Site, highlighting its global cultural significance. The Opera House is also notable for its use of cutting-edge engineering solutions, such as the use of seawater for temperature control and the pioneering application of computer-aided design in its construction.
