Old Parliament House, Federal government building in Canberra, Australia

Old Parliament House is a three-storey brick building in Canberra with a white-painted concrete facade and a flat roof with a raised central parapet. Its front shows two storeys of rectangular windows and a central arched window, with higher masses behind marking the two debating chambers. A white pillar sign on a red brick base stands in front, and three flagpoles fly Australian flags to the left.

The building opened in 1927 and served as the seat of Australian Parliament until the government moved to a new building on Capital Hill in 1988. After the relocation, it was converted into a museum preserving the parliamentary history of the country.

The name reflects the building's former role, now preserved as a museum where visitors see how political decisions were made throughout the twentieth century. Original furniture remains in the chambers where members of parliament and senators once debated, showing how daily work unfolded inside these rooms.

The building stands at the foot of Capital Hill inside the Parliamentary Triangle, facing across Lake Burley Griffin toward the Australian War Memorial. The main entrance is reached by a flight of stairs up to King's Hall; the front steps' railings were added only after parliament left in 1988. The Aboriginal Tent Embassy has occupied the lawn in front since 1972.

On the lawn in front of the building, four Aboriginal activists pitched the Aboriginal Tent Embassy on Australia Day 1972, protesting the government's rejection of native title. The unofficial embassy has remained there for decades and is still not officially recognised. It is a detail many visitors walk past without knowing its story.
