Universidad Nacional Autónoma de México (UNAM)
Some of the country's most celebrated modern architects—including Mario Pani, Enrique del Moral, and Teodoro González de Leon—designed buildings on the massive campus of UNAM, which sprawls across its own city within a city, the 2,500-acre (10-square-km) Ciudad Universitaria. Located in the southern reaches of the city, a little south of Coyoacán and San Ángel, the current campus was constructed in the 1950s on a then completely desolate field of petrified lava produced by the roughly AD 300 eruption of Xitle Volcano (a now dormant 1,000-foot-tall ash cone volcano about 8 km [5 miles] to the south). The university itself was established in 1910 and is one of the largest and most prestigious educational institutions in the world, with about 213,000 undergraduate and 30,000 graduate students enrolled across its numerous campuses around the country (as well as in extension schools in the United States and Canada). UNAM accepts only about 8% of applicants, and the campus here at Ciudad Universiteria is by far the largest and includes a number of outstanding architectural works and cultural attractions. Murals by Diego Rivera, David Alfaro Siqueiros, and Juan O'Gorman appear on some buildings, most notably the 1956 functionalist Central Library, which O'Gorman designed in collaboration with Gustavo Saavedra and Juan Martinez de Velasco (and on which his massive murals appear). In addition to its outstanding museums and performance spaces, another highlight on campus is Jardín Botánico. UNAM also operates some other important institutions around the city, including Palacio de Mineria and Colegio de San Ildefonso (with its famous murals) in Centro Histórico, Casa del Lago in Parque Chapultepec, and Museo Universitario del Chopo in Santa Maria la Ribera.
