The capital city of Australia is Canberra. It was founded following the federation of the Australian colonies as the seat of government for the new nation and is located in the Australian Capital Territory (ACT). Canberra is Australia's largest inland city and the eighth-largest city overall. It was formally named and established as the capital in 1913 after a design competition won by American architects Walter Burley Griffin and Marion Mahony Griffin. The city is a planned city, uniquely designed with geometric motifs centered on significant landmarks. It serves as the seat of the federal government and hosts many national institutions, including Parliament House, the Australian War Memorial, and the National Gallery of Australia
