<p>Unusual among Australian cities, it is an entirely planned city. The city is located at the northern end of the Australian Capital Territory[11] at the northern tip of the Australian Alps, the country's highest mountain range. As of June 2020, Canberra's estimated population was 431,380.[12]</p><p>The area chosen for the capital had been inhabited by Indigenous Australians for up to 21,000 years,[13] with the principal group being the Ngunnawal people. European settlement commenced in the first half of the 19th century, as evidenced by surviving landmarks such as St John's Anglican Church and Blundells Cottage. On 1 January 1901, federation of the colonies of Australia was achieved. Following a long dispute over whether Sydney or Melbourne should be the national capital,[14] a compromise was reached: the new capital would be built in New South Wales, so long as it was at least 100 miles (160 km) from Sydney. The capital city was founded and formally named as Canberra in 1913. A blueprint by American architects Walter Burley Griffin and Marion Mahony Griffin was selected after an international design contest, and construction commenced in 1913.[15] The Griffins' plan featured geometric motifs and was centred on axes aligned with significant topographical landmarks such as Black Mountain, Mount Ainslie, Capital Hill and City Hill. Canberra's mountainous location makes it the only mainland Australian city where snow-capped mountains can be seen in winter; although snow in the city itself is rare.</p><p>As the seat of the Government of Australia, Canberra is home to many important institutions of the federal government, national monuments and museums. This includes Parliament House, Government House, the High Court and the headquarters of numerous government agencies. It is the location of many social and cultural institutions of national significance such as the Australian War Memorial, the Australian National University, the Royal Australian Mint, the Australian Institute of Sport, the National Gallery, the National Museum and the National Library. The city is home to many important institutions of the Australian Defence Force including the Royal Military College Duntroon and the Australian Defence Force Academy. It hosts all foreign embassies in Australia as well as regional headquarters of many international organisations, not-for-profit groups, lobbying groups and professional associations.</p>
