31st Street Beach on the Lake Michigan waterfront, and historical buildings from the heyday of the Black Metropolis era, including the Chicago Bee Building, the Eighth Regiment Armory, and the Overton Hygienic Building. The campus is bordered on the west by the Chicago 'L' Red Line, which runs parallel to Lake Michigan north to Rogers Park and south to 95th street. The Green Line bisects the campus and runs north to the Loop and then west to the near west suburbs and south to the Museum Campus and the University of Chicago. Today, Illinois Tech continues to support the Historic Bronzeville area by sponsoring non-for-profits such as The Renaissance Collaborative. Architecture The campus, roughly bounded between 31st and 35th streets, Michigan Avenue, and the Dan Ryan Expressway, was designed by modernist architect Ludwig Mies van der Rohe, "one of the great figures of 20th-century architecture," who chaired the IIT School of Architecture from 1938 to 1958. Van der Rohe's master plan for the Illinois Tech campus was one of the most ambitious projects he ever conceived and the campus, with 20 of his works, is the greatest concentration of his buildings in the world. The layout of the campus departs radically from "traditional college quadrangles and limestone buildings". The materials are inspired by the factories and warehouses of Chicago's South Side and "embod[y] 20th century methods and materials: steel and concrete frames with curtain walls of brick and glass." The campus was landscaped by van der Rohe's close colleague at Illinois Tech, Alfred Caldwell, "the last representative of the Prairie School of landscape architects." Known as "the nature poet", Caldwell's plan reinforced van der Rohe's design with "landscaping planted in a free-flowing manner, which in its interaction with the pristine qualities of the architecture, introduce[d] a poetic aspect." On the west side of Mies Campus are three red brick buildings that were original to Armour Institute, built between 1891 and 1901. In 1938 Ludwig Mies van der Rohe began his 20-year tenure as director of IIT's School of Architecture (1938–1959). The university was on the verge of building a brand new campus, to be one of the nation's first federally funded urban renewal projects. Mies was given carte blanche in the large commission, and the university grew fast enough during and after World War II to allow much of the new plan to be realized. From 1943 to 1957, several
