The Chicago Federal Center, designed by Ludwig Mies van der Rohe and completed in 1974, actually consists of three buildings which are arranged around and define the Chicago Federal Plaza. On the eastern side of South Dearborn Street sits the 30-story Everett M. Dirksen U.S. Courthouse. On the western side, the 42-story John C. Kluczynski Federal Building and the single story Post Office define the plaza.
