The main campus of the University of Chicago consists of 217 acres (87.8 ha) in the Chicago neighborhoods of Hyde Park and Woodlawn, approximately eight miles (12 km) south of downtown Chicago. The northern and southern portions of campus are separated by the Midway Plaisance, a large, linear park created for the 1893 World's Columbian Exposition. In 2011, Travel+Leisure listed the university as one of the most beautiful college campuses in the United States.[82] Aerial shots from the University of Chicago campus.

The first buildings of the campus, which make up what is now known as the Main Quadrangles, were part of a master plan conceived by two University of Chicago trustees and plotted by Chicago architect Henry Ives Cobb.[83] The Main Quadrangles consist of six quadrangles, each surrounded by buildings, bordering one larger quadrangle.[35]: 221  The buildings of the Main Quadrangles were designed by Cobb, Shepley, Rutan and Coolidge, Holabird & Roche, and other architectural firms in a mixture of the Victorian Gothic and Collegiate Gothic styles, patterned on the colleges of the University of Oxford.[83] (Mitchell Tower, for example, is modeled after Oxford's Magdalen Tower,[84] and the university Commons, Hutchinson Hall, replicates Christ Church Hall.[85]) In celebration of the 2018 Illinois Bicentennial, the University of Chicago Quadrangles[86] were selected as one of the Illinois 200 Great Places by the American Institute of Architects Illinois component (AIA Illinois).[87]
