About Chicago

Chicago is a major city in the United States, situated in the Midwest region, on the southwestern-most tip of Lake Michigan. It was incorporated as a city in 1837. Today, with a population of 2.7 million, it is the third largest city in the country, after New York City and Los Angeles. As would be expected of a large city, Chicago has a rich culture and several landmarks including Navy Pier, the Magnificent Mile, Millennium Park, the Art Institute of Chicago, and the Museum Campus, among others. Perhaps one of the most familiar of the city’s landmarks is the Willis (Sears) Tower, which held the title of tallest building in the world for nearly 25 years since its completion in 1974. In fact, the city’s connection to skyscrapers began over a century ago, when it became home to the first steel-frame skyscraper, the Home Insurance Building, (originally 10 stories with a height of 42 m or 138 ft) in 1885. Therefore, it is only fitting that the Council on Tall Buildings and Urban Habitat relocated its Headquarters to Chicago in 2003.
