"Ciudad Universitaria" (University City) is UNAM's main campus, located within Coyoacán borough in the southern part of Mexico City. Designed by architects Mario Pani, Enrique del Moral, Domingo García Ramos, Armando Franco Rovira and others, it encloses the Estadio Olímpico Universitario, about 40 faculties and institutes, the Cultural Center, an ecological reserve, the Central Library, and a few museums. It was built during the 1950s on an ancient solidified lava bed to replace the scattered buildings in downtown Mexico City where classes were given. It was completed in 1954 and is almost a separate region within Mexico City, with its own regulations, councils, and police (to some extent) in a more fundamental way than most universities around the world. Law enforcement officials from outside the university are not allowed to enter without the consent of the university authorities.
In June 2007, its main campus, Ciudad Universitaria, was declared a UNESCO World Heritage Site.
