Chase Tower, located in the Chicago Loop area of Chicago at 10 South Dearborn Street, is a 60 story skyscraper completed in 1969. At 850 feet (259 m) tall, it is the tenth tallest building in Chicago, the tallest building inside the Chicago 'L' Loop elevated tracks, and the 32nd tallest in the United States. Chase Bank has its U.S. and Canadian commercial and retail banking headquarters here. The building is also the headquarters of Exelon. The building and its plaza (known as Exelon Plaza) occupy the entire block bounded by Clark, Dearborn, Madison, and Monroe Streets.
Design architects for the construction were C.F. Murphy Associates, Stanislaw Z. Gladych and Perkins and Will. Chase Tower is known for both its distinctive curving shape and its vibrant public space: a deep sunken plaza at the geographic center of the Chicago Loop, complete with a jet fountain and Marc Chagall's ceramic wall mural Four Seasons.
