Parliament House is the meeting facility of the Parliament of Australia located in Canberra, the capital of Australia. The building was designed by Mitchell/Giurgola Architects and opened on 9 May 1988 by Elizabeth II, Queen of Australia. At the time of the construction, it was the most expensive building in the World at more than A$1.1 billion.
It contains 4,700 rooms and many areas are open to the public. The main foyer contains a marble staircase and leads to the Great Hall which has a large tapestry on display. The House of Representatives chamber is decorated green while the Senate chamber has a red colour scheme. Between the two chambers is the Members' Hall which has a water feature and is not open to the public. The Ministerial Wing houses the office of the Prime Minister and other Ministers.
