About Chase Tower
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. Design architects for the construction were C.F. Murphy Associates and Perkins and Will. The building has the headquarters of Exelon. The building formerly had the headquarters of the Bank One Corporation. The building and its plaza (known as Exelon Plaza) occupy the entire block bounded by Clark, Dearborn, Madison, and Monroe Streets. 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. The building's name was changed from Bank One Tower on October 24, 2005, as a result of a corporate merger. Earlier the plaza was named First National Plaza. When constructed it was home to the First National Bank of Chicago. Since May 2005 the National Public Radio show Wait Wait... Don't Tell Me!
