Started in 1959 and not finished until 1973 by Danish architect Jorn Utzon, the Sydney Opera House is one of the most famous performing arts centres in the world. Its concrete plaster "shells" (or structurally panels) represent modern expressionism and a highly technical design. The Opera House actually contains multiple venues for symphony, opera, theater and other performing arts while also becoming the national icon of Sydney surrounded by the harbour on three sides.
