The Alma Mater, a bronze statue by sculptor Lorado Taft, is a beloved symbol of the University of Illinois Urbana-Champaign. The 10,000-pound statue depicts a mother-figure wearing academic robes and flanked by two attendant figures representing "Learning" and "Labor", after the university's motto "Learning and Labor." Sited at the corner of Green and Wright Streets at the heart of the campus, the statue is an iconic figure for the university and a popular backdrop for student graduation photos. It is appreciated for its romantic, heraldic overtones and warmth of pose. The statue was removed from its site at the entrance to the university for restoration in 2012 and was returned to its site in the spring of 2014.

The Natural History Building is a historic building on the campus of the University of Illinois at Urbana–Champaign in Urbana, Illinois. Built in 1892, the building originally housed the university's departments of botany, zoology, and geology. In addition to classroom space, the building also included a natural history museum. Architect Nathan Clifford Ricker designed the High Victorian Gothic building. The red brick building has a rough stone foundation and is decorated with colored brick and stone. The steep roof is supported by a timber truss system; the exposed trusses create a coffered ceiling on the interior.The building was added to the National Register of Historic Places on November 9, 1986. In 2010, it was evacuated due to structural deficiencies. After an extensive, $79 million renovation, it reopened in August 2017 and now houses the School of Earth, Society, and Environment (SESE) including the Departments of Atmospheric Sciences, Geology and Geography and Geographic Information systems, as well as teaching space for the School of Integrative Biology (SIB). In 2019, the building received Leadership in Energy and Environmental Design Gold status for its renovation being conducted in an environmentally efficient manner, which included using renewable materials, utilizing energy-efficient technology, and focusing on natural lighting.

The William Albert Noyes Laboratory of Chemistry, located on the campus of the University of Illinois Urbana-Champaign at 505 S. Mathews Avenue in Urbana, Illinois, United States, was built in 1902 as the "New Chemical Laboratory", and was designed by Nelson Strong Spencer in the Richardsonian Romanesque style. Founded in 1867, the Chemistry Department was the first department of the university to move into its own building in 1878. When the department outgrew that building, department head Arthur W. Palmer convinced the state legislature to build a new lab, with 77,884 square feet of usable space, at a cost of under $100,000.Ten years later, when more space was needed,the east wing—with 86,396 square feet of additional space—was built in 1915–16 at the cost of $250,000. The building then housed the largest chemistry department in the United States at the time. At various times, the buildings also housed the departments of Biochemistry, Chemical Engineering and Bacteriology, as well as the Illinois Water Survey.In 1939 the building was dedicated in honor of the influential UI chemist William A. Noyes. It was designated a National Historic Chemical Landmark by the American Chemical Society in 2002, in recognition of the many contributions to the chemical sciences that have been made there over the last 100 years. In 1930, James McLaren White's Chemistry Annex Building was completed, and connected to the Noyes Lab Building underground. It added 39,000 square feet at the cost of $335,000, and in 1951 the East Chemistry Annex was added to the complex, at the cost of $5.9 million.
