Introduction to the Old Parliament Building: The Old Parliament House (Old Parliament House) was built in 1927. It is the federal parliament building and has had two major expansions. Since the new Parliament Building was completed in 1988, it has completed its 61-year mission and become a historical museum. The Old Parliament Building is a witness and milestone in Australia's political history. From 1927 to 1988, all debates and decisions on major international and domestic events were passed here. This two-story white building has two main parts: the conference hall and offices of the Legislative Department, and the restaurant and bar for rest and entertainment.
