The competition
The competition for a national opera house was launched on 13 September 1955 and drew 233 entries from 32 countries. Jørn Utzon, a Danish architect, was announced the winner on 29 January 1957.
A long build
Construction began in March 1959. Utzon left the project in February 1966, and Peter Hall became largely responsible for the interior design. The first opera, Prokofiev’s War and Peace, was performed on 28 September 1973.
An opening and a listing
Queen Elizabeth II formally opened the building on 20 October 1973. It was added to the NSW State Heritage Register in 2003, the National Heritage List in 2005 and the UNESCO World Heritage List in 2007.
