===Chicago Federal Complex===
[[File:Chicago Federal Center.jpg|thumb|[[Chicago Federal Center]], built 1964–1974]]
Chicago Federal Center Plaza, also known as Chicago Federal Plaza, unified three buildings of varying scales: the mid-rise [[Everett McKinley Dirksen United States Courthouse]], the high-rise [[Kluczynski Federal Building|John C. Kluczynski Building]], and the single-story Post Office building. The complex's plot area extends over two blocks; a one-block site, bounded by Jackson, Clark, Adams, and Dearborn streets, contains the Kluczynski Federal Building and U.S. Post Office Loop Station, while a parcel on an adjacent block to the east contains the Dirksen U.S. Courthouse.  The structural framing of the buildings is formed of high-tensile bolted steel and concrete. The exterior curtain walls are defined by projecting steel I-beam mullions covered with flat black graphite paint, characteristic of Mies's designs. The balance of the curtain walls are of bronze-tinted glass panes, framed in shiny aluminum, and separated by steel spandrels, also covered with flat black graphite paint.<ref>{{cite web |url= http://www.gsa.gov/portal/ext/html/site/hb/category/25431/actionParameter/exploreByBuilding/buildingId/1062 |title= John C.

This pattern extends from the granite-paved plaza into the ground-floor lobbies of the two tower buildings with the grid lines continuing vertically up the buildings and integrating each component of the complex.  Associated architects that have played a role in the complex's long history from 1959 to 1974 include Schmidt, Garden & Erickson; C.F. Murphy Associates; and A. Epstein & Sons.<ref>{{cite web|url=http://tclf.org/landscapes/federal-plaza |title=Chicago Federal Center Plaza|access-date=July 14, 2015}}</ref>
