Old Parliament House was the seat of Australian Parliament from 1927 to 1988, and now houses the Museum of Australian Democracy. Located in the heart of the Parliamentary Triangle, the museum celebrates the spirit of Australian democracy through interactive exhibitions telling the stories of social movements, policy-making, and the voices that shaped the nation. Visitors can explore the historic House of Representatives and Senate chambers, the Prime Minister's office, and committee rooms. Positioned between the new Parliament House and War Memorial on the famous land axis, it's a pivotal landmark in understanding Australia's political heritage.
