55 W Randolph St.
The Daley Center (originally known as the Chicago Civic Center) is an exceptional example of International Style architecture, based on the revolutionary steel and glass skyscrapers of world-famous architect Ludwig Mies van der Rohe. The building, Chicago's first major public building to be constructed in a modern rather than a classical architectural style, was designed by C. F. Murphy Associates whose work was influential in Chicago during the 1960s and 70s. Innovative for its time are the building's huge spans of steel framing, its exceptional spatial flexibility and the first-ever use of self-weathering Cor-Ten steel as an exterior "skin" for a skyscraper.
