Chicago

Architecture

The outcome of the Great Chicago Fire led to the largest building boom in the history of the nation. Perhaps the most outstanding of these events was the relocation of many of the nation's most prominent architects to the city from New England for construction of the 1893 World Columbian Exposition.

In 1885, the first steel-framed high-rise building rose in Chicago ushering in the skyscraper era.[28] Today, Chicago's skyline is among the world's tallest and most dense.[29] Downtown's historic buildings include the Chicago Board of Trade Building in the Loop, with others along the lakefront and the Chicago River. Once first on the list of largest buildings in the world and still listed twentieth, the Merchandise Mart stands near the junction of the north and south river branches. Presently the four tallest in the city are the Sears Tower, Trump International Hotel and Tower, the Aon Center (previously the Standard Oil Building), and the John Hancock Center. The city's architecture includes lakefront high-rise residential towers, low-rise structures, and single-family homes. Industrialized areas such as the Indiana border, south of Midway Airport, and the banks of the Chicago Sanitary and Ship Canal are clustered. Future skyline plans entail the supertalls Waterview Tower, and the Chicago Spire.
