Canberra was started in 1913 and in the middle of the city is Lake Burley-Griffin . This lake was created especially for the city. There was a competition to design the new capital city of Australia. The competition was won by an architect from Chicago in the United States of America. His name was Walter Burley Griffin. Griffin designed his triangular town as a garden town, so its size expanded over a big area. But as Canberra grew larger and larger, the lake was no longer in the middle of the town, but the people who are in charge of planning the city make sure Canberra is as close to Griffin's original plan as possible. Canberra has a size in area nearly as big as Berlin, but the number of people who live there is much smaller.
