This museum hosts temporary exhibits of contemporary Mexican and international artists, as well as rotating displays from its permanent art collection.
The Museo Universitario Arte Contemporáneo, also known as MUAC, is a large contemporary art museum located within the main campus of the National Autonomous University of Mexico (UNAM). It opened in November 2008 and it is the first Mexican public museum exclusively focused to the arts created in the XXI century.

Sometimes dubiously described as the world's largest outdoor sculpture, the Espacio Escultórico is a round ring reminiscent of a modernized Stonehenge. It is a wide path lined with angular stone monoliths surrounding a patch of natural volcanic rock.
UNAM Botanical Garden
Large botanical garden showcasing thousands of plant species from across Mexico's many different ecosystems, including dry deserts, rocky mountain ranges, tropical and sub-tropical rainforests, and coastal wetlands. The gardens include an extensive collection of cacti. Visitors may be surprised at the extent of the collection (and Mexico's astounding biodiversity - the country is home to more plant and animal species than both the United States and Canada combined).
Comprehensive science and technology museum with exhibits for all ages. Paleontology (dinosaur bones), astronomy (includes a planetarium), chemistry, physics, there are even exhibits that make math look like fun! It's a large museum, so plan to spend most of the day here.
MUCA
Open interdisciplinary exhibition space. Typically has an exhibition on a specific topic for a period of a few months, then shuts down until a new exhibition is prepared. (Check the official website for events, other sources are unreliable.)
Rectory building of UNAM
For David Alfaro Siqueiros fans, the rectory building is of interest because of its large three-dimensional mosaic mural El pueblo a la Universidad, la Universidad al pueblo (The People to the University, the University to the People), created by the Mexican master from 1952-1956.
Museum of Pathological Anatomy
Three-legged chickens, cats born with 1 eye, organs destroyed by tapeworms, these are just a few of the gross biological deviances that you'll see on display in this very strange and unsettling museum. Guided tours available.
