On 20th of October 1973  Queen Elizabeth opened the Sydney Opera House at Bennelong Point in Sydney, Australia, after 14 years of construction.

Sydney Opera House was designed by Danish architect Jørn Utzon and completed by an Australian architectural team headed by Peter Hall.

The building comprises multiple performance venues, which together host well over 1,500 performances annually, attended by more than 1.2 million people.

On 28 June 1998 the Sydney Opera House became a UNESCO World Heritage Site, and its social asset value is estimated by Deloitte at $11.4 billion.
