Some of the buildings have a "concrete jungle" look, amidst the green of campus lawns, as shown in the next two photos.
To my mind, the most important structure on the UIC campus is Jane Addams's Hull House, most active from 1889-1935 from what I can gather, and now remaining only as a museum (official website, Wikipedia page). Described as providing "innovative social, educational, and artistic programs" for recently arrived immigrants in the neighborhood, Hull House also served as a launching pad for social reformers and activists to formulate policy ideas.
The Hull-House complex long predated UIC in its Near West Side location. In fact, construction of the present UIC campus in the 1960s required demolition of most of the Hull-House complex. According to this 1994 Chicago Tribune article:
In 1963, the Hull House Association sold its 13-building complex, all on the 800 block of South Halsted, to the City of Chicago as a prelude to construction of UIC. Eleven buildings fell to the wrecker's ball. Only a national protest saved the remaining two, the former mansion of real estate dealer Charles Hull and the Residents' Dining Hall.
