Illinois Institute of Technology Academic Campus
Also known as: Armour Institute of Technology

Why it's listed
Illinois Institute of Technology's academic campus occupies about 60 acres in Chicago's Douglas neighborhood, on the South Side. Twenty-six buildings make up the district: three from the Armour Institute of Technology era, fourteen designed by Mies van der Rohe, and nine added afterward. The oldest are the Main Building (1891-93), Machinery Hall (1901) and the Maintenance Garage (1901), all by Patten & Fischer, with the first two in Richardsonian Romanesque style. Mies planned the campus on a twenty-four foot by twelve foot modular grid, and his buildings use black painted steel, glass and buff brick, with the structure left visible. S.R. Crown Hall departs from that pattern with a steel and glass enclosure spanning clear of interior supports. Skidmore, Owings and Merrill and Schmidt, Garden and Erikson later built in a similar manner. The campus is listed for its link to Mies's planning and teaching and for its influence on architecture in the United States and abroad.
Significance in brief: The nomination argues the campus is nationally significant as the master plan and architecture of Mies van der Rohe, where he developed and refined his design principles, including a modular grid, expressed steel structure and the clear-span S.R. Crown Hall. It also contains three earlier Richardsonian Romanesque buildings from Armour Institute of Technology, and later buildings by SOM and Schmidt, Garden and Erikson that followed Mies's vocabulary. Mies's teaching and planning at IIT strongly influenced American and world architecture.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
