List of tallest buildings in Chicago

This list of tallest buildings in Chicago ranks skyscrapers by height in the U.S. city of Chicago, Illinois, which is considered to be the birthplace of the skyscraper.[1][2] The tallest building in Chicago is the 110-story Willis Tower (formerly Sears Tower), which rises 1,454 feet (443 m) in the Chicago Loop and was completed in 1974.[3] It also stands as the tallest building in the United States, rising 1,730 feet (527 m) with the addition of its western antenna.[4] The second-, third- and fourth-tallest buildings in Chicago are the Trump International Hotel & Tower, the Aon Center and the John Hancock Center, respectively. The history of skyscrapers in Chicago began with the 1885 completion of the Home Insurance Building, which is often regarded as the first steel-framed skyscraper in the world. The building was originally constructed with a height of 138 feet (42 m) and 10 stories, and was later expanded to a height of 180 feet (55 m) and 12 stories before being demolished in 1931.[5][6] Historically, Chicago has played a prominent role in the development of the skyscraper. The Masonic Temple Building was the tallest building in the world using the unconventional definition that excludes the New York World Building's ornamental lantern.[7] Three past buildings have been considered the tallest building in the United States, including the Chicago Board of Trade Building, which in both of its incarnations held the title of Chicago's tallest building.[8] Chicago went through a very early high-rise construction boom that lasted from the early 1920s to the mid-1930s, during which time 11 of the city's 91 tallest buildings were constructed. The city then went through an even larger building boom that has lasted from the early 1960s until the present. The high-rises that have been constructed are mostly concentrated in the Loop and along the Magnificent Mile in Chicago's Near North Side community area. Overall, the skyline of Chicago is ranked (based on existing and under-construction buildings over 492 feet (150 m) tall) first in the Midwestern United States and second in the United States, after New York City.[B] As of July 2011, there were 1,125 completed high-rises in the city, second in the country behind New York.[9] Based on the average height of the ten tallest completed buildings, Chicago has the tallest skyline in the world.[10]

Chicago has another building under construction that is planned to exceed 1,000 feet (304.8 m) in height, though construction has been on hold, with the building incomplete, since early 2008: the 1,047-foot (319 m) Waterview Tower.[11] The 150-story Chicago Spire, originally planned for completion in 2012, has been canceled.[12]

Tallest buildings by pinnacle height

This list ranks Chicago skyscrapers based on their pinnacle height, which includes radio masts and antennas. As architectural features and spires can be regarded as subjective, some skyscraper enthusiasts prefer this method of measurement. Standard architectural height measurement, which excludes antennas in building height, is included for comparative purposes.
