2021 $1 National Heritage Australia - Sydney Opera House Coin & Stamp Cover PNC.Australia's most famous building, the Sydney Opera House, was formally opened by Her Majesty Queen Elizabeth II in 1973.Acclaimed throughout the world, this great modernist masterpiece was designed by Danish architect Jorn Utzon, who was awarded the project in 1957 by an international jury.With its prominent location on Bennelong Point, the building is a fitting response to its spectacular harbour setting.It comprises three groups of interlocking, vaulted 'shells', which roof two main performance halls and a resturant.These are set on a vast platform and are surrounded by a terrace that functions as a pedestrian concourse.The building's dynamic structure resembles sails or a giant bird about to take flight. After his resignation from the project in 1966, Utzan returned in 1999 to restore the interior to his original vision.In 2003, Utzon received the Pritzker Prize, architecture's highest honour.The Sydney Opera House was inscribed on the National Heritage List in 2005 and on the UNESCO World Heritage List in 2007 as 'a masterpiece of 20th century architecture".The stamp and coin cover features an illustrated envelope featuring the historic Sydney Opera House it also includes an Australian $1.10c commemorative stamp and is post marked First Date of Issue 10 May 2021 Capitol Hill ACT 2600.Denomination :        $1Metal :                     Aluminium BronzeWeight :                  9gmDiameter :               25 mmMintage :                 6,500Australia Post Seal of Authenticity
