Sydney Opera House is a multi-venue performing arts centre in Sydney. It was conceived and largely built by Danish architect Jørn Utzon, who received the Pritzker Prize, architecture's highest honour in 2003. Sydney Opera House is a UNESCO World Heritage Site. Currently, it is the most recently constructed World Heritage Site to be designated as such, sharing this distinction with such ancient landmarks as Stonehenge and the Giza Necropolis. It is one of the 20th century's most distinctive buildings and one of the most famous performing arts centres in the world. It is also one of the busiest performing arts centres in the world, providing over 1,500 performances each year attended by some 1.2 million people.
