Why go
Walk around the building to follow four mural facades that compress Mexico's past, the modern nation, the university and the cosmos into a single architectural work. The library also makes the World Heritage campus's idea of integrating art, landscape and modern design immediately legible.
What to look for
- Circle the building to read all four mosaic facades.
- Notice how volcanic stone and colored rock connect the tower to the campus landscape.
- Frame the library with the open lawns of Las Islas.
The full story
Architects Juan O'Gorman, Gustavo Saavedra and Juan Martínez de Velasco designed the library during the creation of Ciudad Universitaria after 1948. Its most memorable element is the windowless book stack, which O'Gorman treated as four enormous mural surfaces. Instead of paint, he assembled the images from naturally colored stones gathered in different parts of Mexico, giving the facades a durable texture that changes with distance and light. The compositions connect pre-Hispanic imagery, colonial history, the modern nation, the university and scientific thought. This union of architecture and visual art embodies the campus principle known as plastic integration. Seen from Las Islas, the compact mosaic tower contrasts with the long horizontal reading rooms below it. The building remains a working library as well as the most recognizable visual symbol of UNAM and its World Heritage campus.
Useful to know
- The exterior is the main visitor experience and works best in daylight.
