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

Performing arts center/centre, often abbreviated as PAC, is used to refer to:A multi-use performance space that is intended for use by various types of performing arts, including dance, music and theatre.The intended multiple use of performing arts centers in this sense differentiates them from single-purpose concert halls, opera houses or theatres, although the actual use of single-purpose spaces for other than their intended use is widespread. This sort of space has a long history, extending to the Roman Colosseum and Greek amphitheatres.A cluster of performance spaces, either separate buildings or under one roof, each space designed for a specific purpose such as symphonic music or chamber music or theatre, but multipurpose as a whole. The modern version of this came into being only in the 1960s.Examples of this type of PAC are the Kennedy Center in Washington, D.C., the Sydney Opera House, and the Lincoln Center in New York City.
