Walter Burley Griffin planned Canberra as Australia's capital city based on his winning design in an international competition in 1912. His plan featured bisecting land and water axes, with Parliament House at the intersection. It was influenced by designs of Washington D.C. and Chicago, incorporating wide tree-lined avenues and an artificial lake. Construction began in 1913 but faced challenges from changes in government and World War I that slowed progress until the legislature moved to Canberra in 1927.
