The Sydney Opera House in Sydney, Australia, is designed by which of the following architects?

The Sydney Opera House is a multi-venue performing arts center in Sydney, New South Wales, Australia. Located on the foreshore of Sydney Harbor, it is widely regarded as one of the world's most famous and distinctive buildings and a masterpiece of 20th-century architecture.

Designed by Danish architect and Pritzker Prize laureate (2003) Jørn Utzon (1918 - 2008) and completed by an Australian architectural team headed by Peter Hall, the building was opened by Queen Elizabeth II on 20 Oct 1973, 16 years after Utzon's 1957 selection as winner of an international design competition.

The building features a modern expressionist design, with a series of large precast concrete "shells", each composed of sections of a sphere of 75.2m (246 ft 8.6 in) radius, forming the roofs of the structure, set on a monumental podium. It covers 1.8 hectares (4.4 acres) of land and is 183m (600 ft) long and 120m (394 ft) wide at its widest point.

Utzon had a Nordic sense of concern for nature which, in his design, emphasized the synthesis of form, material and function for social values. His fascination with the architectural legacies of the ancient Mayas, the Islamic world, China, and Japan also informed his practice.

When the Sydney Opera House was declared a World Heritage Site on 28 Jun 2007, Utzon became only the 2nd person to have received such recognition for one of his works during his lifetime, after Brazilian architect & Pritzker Prize Laureate (1988) Oscar Niemeyer (1907 - 2012).
