2019, the university created its first school in three decades, the Pritzker School of Molecular Engineering. Campus Main campus The main campus of the University of Chicago consists of in the Chicago neighborhoods of Hyde Park and Woodlawn, approximately 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. 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. The Main Quadrangles consist of six quadrangles, each surrounded by buildings, bordering one larger quadrangle. 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. (Mitchell Tower, for example, is modeled after Oxford's Magdalen Tower, and the university Commons, Hutchinson Hall, replicates Christ Church Hall.) In celebration of the 2018 Illinois Bicentennial, the University of Chicago Quadrangles were selected as one of the Illinois 200 Great Places by the American Institute of Architects Illinois component (AIA Illinois). After the 1940s, the campus's Gothic style began to give way to modern styles. In 1955, Eero Saarinen was contracted to develop a second master plan, which led to the construction of buildings both north and south of the Midway, including the Laird Bell Law Quadrangle (a complex designed by Saarinen); a series of arts buildings; a building designed by Ludwig Mies van der Rohe for the university's School of Social Service Administration, a building which is to become the home of the Harris School of Public Policy by Edward Durrell Stone, and the Regenstein Library, the largest building on campus, a brutalist structure designed by Walter Netsch of the Chicago firm Skidmore, Owings & Merrill. Another master plan, designed in 1999 and updated in 2004, produced the Gerald Ratner Athletics Center (2003), the Max Palevsky Residential Commons (2001), South Campus Residence Hall and dining commons (2009), a new children's hospital, and other construction, expansions, and restorations. In 2011, the university completed the glass dome-shaped Joe and Rika Mansueto
