The Sydney Opera House Opens

On 20 October 1973, Queen Elizabeth II formally opened the Sydney Opera House on Bennelong Point in Sydney Harbour. The ceremony concluded a fraught, sixteen-year construction project that had transformed an ambitious design competition entry into one of the most recognizable public structures in the world. Initiated in the late 1940s after lobbying by conductor Eugene Goossens for a dedicated municipal performance venue, the development received official support from New South Wales Premier Joseph Cahill, whose government opened an international design competition in February 1956. In January 1957, Danish architect Jørn Utzon was announced as the winner from more than 220 entries submitted from around the world, chosen by an assessment panel that included Finnish-American architect Eero Saarinen.

Utzon envisioned a sculptural facility composed of soaring, curved roof shells situated atop an expansive base. Following the demolition of the Fort Macquarie Tram Depot, work commenced in March 1959 under the management of Civil and Civic and engineering consultants Ove Arup and Partners. The state government had pressured the team to begin construction before detailed engineering drawings were complete, worried that funding or public backing might falter. Consequently, early progress suffered extensive setbacks; by January 1961, building was 47 weeks behind schedule, and the initial podium columns lacked sufficient strength to hold the weight of the roofs, necessitating significant reconstruction.
