The murals of UNAM’s Ciudad Universitaria turn an entire campus into a lesson in Mexican art and history. Monumental mosaics cover the Biblioteca Central, dynamic compositions animate the Torre de Rectoría and a stone relief transforms the entrance of the Estadio Olímpico Universitario.

These works were designed for public space. Their scale and composition unfold as you walk around them, watch their images change with distance and discover how each artist responded to the architecture around him.

This guide explains the three essential stops, the ideas behind the murals and what you need to know before visiting UNAM independently.

Why are the UNAM murals are so important?

Ciudad Universitaria was constructed between 1949 and 1952 through the collaboration of more than 60 architects, engineers and artists. The project brought modern architecture, urban planning, landscape design and monumental art together while drawing on Mexico’s pre-Hispanic heritage. UNESCO added the central campus to the World Heritage List in 2007, recognizing it as a major example of 20th-century modernism in Latin America.

The key concept behind the campus is integración plástica, or plastic integration. The murals were conceived in dialogue with the buildings and their functions, embedding art into the architecture, materials and movement of the campus. This relationship is what makes UNAM different from a traditional museum. The library becomes a visual history of knowledge, the administrative tower presents education as a public responsibility and the stadium connects sport with national identity.

Juan O'Gorman's Biblioteca Central Mural

The Biblioteca Central is the most recognizable building at UNAM and one of the defining images of Mexico City. Juan O’Gorman designed the building with architects Gustavo María Saavedra and Juan Martínez de Velasco, then transformed its windowless book-storage tower into a monumental artwork.

His mosaic, Representación histórica de la cultura, dates from 1952 and covers approximately 4,000 square meters. It was assembled from prefabricated concrete panels using more than 150 types of naturally colored stone and glass collected from different parts of Mexico. The material gives the mural its earthy, textured appearance and allows the color to withstand exposure to the elements.

What do the four façades represent?

The mural should be read by walking around the entire building. Each side presents a different chapter in the development of Mexican culture:

• North façade — the pre-Hispanic past: Indigenous deities, symbols, architecture and systems of knowledge create a vision of Mesoamerican civilization before the arrival of the Spanish.
• South façade — the colonial past: Images connected with conquest, Christianity and European rule show the cultural and intellectual tensions of New Spain.
• East façade — the contemporary world: Modern industry, science, conflict and political ideologies place Mexico within the turbulent international history of the 20th century.
• West façade — the University and modern Mexico: The composition connects national identity, education and the role of UNAM in the country’s future.

The contrast between the north and south sides is especially important. O’Gorman presents different worldviews and visual systems, then uses the east and west façades to move the narrative toward modernity and the University.

How to look at the Biblioteca Central

Begin at a distance so you can see how the mosaic turns the tower into a single sculptural object. Then walk closer and look for the smaller symbols embedded throughout the composition. The work becomes less like one picture and more like a visual archive: history, mythology, politics, science and university identity occupy the same architectural surface.

Allow more time if you want to study all four sides. Many visitors photograph only the most familiar façade and miss three quarters of the work.

David Alfaro Siqueiros at the Torre de Rectoria

Beside the Biblioteca Central stands the Torre de Rectoría, where David Alfaro Siqueiros created three works between 1952 and 1956. Two were completed and one remained unfinished. Their sharp angles, projecting forms and forceful gestures reflect Siqueiros’s interest in art experienced through motion.

He developed compositions for viewers, using what he called a polyangular approach. For this reason, these murals make more sense when you move in front of them instead of observing from only one position.

El pueblo a la Universidad, la Universidad al pueblo

The full title continues: Por una cultura nacional neohumanista de profundidad universal. Located on the south side of the tower, the mural presents education as a social responsibility. Its figures suggest that the knowledge produced by students, teachers, scientists and artists should serve the wider public.

Siqueiros used projecting sections of mosaic to create a hybrid between painting and sculpture. He called this approach escultopintura. The work changes as you cross the plaza, reinforcing the idea that muralism belongs to active public life.

El derecho a la cultura, or Las fechas en la historia de México

On the north wall, a monumental hand points toward the dates 1520, 1810, 1857 and 1910, followed by the unresolved inscription 19??. Instead of presenting history as complete, Siqueiros leaves the next transformative moment open.

The question marks invite viewers to consider how history is made and what social change may come next. This unfinished date is one of the most direct examples of the political and participatory character of Mexican Muralism.

Nuevo símbolo universitario

The eastern mural reinterprets UNAM’s emblem through the Mexican eagle and Andean condor, symbols associated with the unity of Latin America. The work remained incomplete, and its visible structure offers an unusual opportunity to see part of Siqueiros’s compositional process.

The best way to view the Siqueiros murals

Walk slowly around the Rectoría and change your angle several times. Look at how hands, arms and diagonals direct your eye beyond the limits of each wall. Siqueiros wanted the building, mural and moving spectator to form one visual experience.

Diego Rivera at the Estadio Olimpico Universitario

The Estadio Olímpico Universitario was designed by Augusto Pérez Palacios, Raúl Salinas Moro and Jorge Bravo Jiménez as a structure shaped by the volcanic landscape of El Pedregal. Diego Rivera described it as an “architectural crater” and created a high-relief mural for its eastern entrance.

Titled La Universidad, la familia y el deporte en México, Rivera’s work is made from naturally colored stones including tezontle, river stone, tecali and marble. The local material unites the relief with the stadium and its volcanic setting.

At the center, the Mexican eagle and Andean condor spread their wings over a family representing mestizaje. The child holds a dove associated with peace. Two athletes raise the Olympic flame, while a feathered serpent decorated with ears of corn refers to Quetzalcóatl and the cultural foundations of ancient Mexico.

Rivera originally planned a much larger composition extending around the stadium and tracing the history of sport from the pre-Hispanic world to modern Mexico. Only the principal section was completed, making the surviving relief both a finished monument and evidence of a more ambitious unrealized project.

The stadium later became the main venue for the 1968 Olympic Games. Its architecture, volcanic materials and Rivera’s mural together express the central ambition of Ciudad Universitaria: to create a modern national project rooted in Mexican history.

Practical information for visiting UNAM

Arriving by Metrobús

Use Line 1 and exit at Ciudad Universitaria. Begin with the Estadio Olímpico Universitario, then continue toward the Torre de Rectoría and Biblioteca Central. The library and Rectoría are beside each other and should be explored together. TThis sequence moves from the volcanic landscape and monumental stadium toward the concentrated architectural center of the campus. You can also reverse the route and finish at the stadium near Avenida Insurgentes.

Arriving by Metro

Take Line 3 to Universidad. This station is on the eastern side of the campus, so allow additional time to reach the central zone. Check the current UNAM transport map before traveling because internal Pumabús routes and operating conditions can change.

How much time do you need?

Allow approximately 45 min - 1.5 hours for the three main sites. The visit duration depends if you plan to enter the Biblioteca Central, explore additional murals or visit the university’s museums and cultural spaces.

Do you need tickets?

The murals described in this guide are located on exterior façades and can be viewed from the campus grounds without a separate museum ticket.

Can visitors enter the Biblioteca Central?

UNAM provides reading-room access to the university community and the general public. Its published service hours are Monday through Sunday and holidays, from 8:30 AM to 9:30 PM, except during administrative vacation periods. The exterior mosaic remains the principal attraction for an art visit. Check the Biblioteca Central’s official information before traveling because access and schedules may change.

When should you visit?

Weekday mornings and early afternoons offer the best sense of university life. Early morning generally provides quieter surroundings for photography. Visit in daylight so you can appreciate the materials and details on every façade.

What should you bring?

Wear comfortable walking shoes and bring water. The campus is extensive and much of the route is outdoors. From June through October, a light rain jacket or umbrella is useful, particularly in the afternoon.

Is the route accessible?

The area around the Biblioteca Central and Rectoría contains broad outdoor spaces, but Ciudad Universitaria is large and the complete route involves considerable walking. Visitors with limited mobility should plan transportation between the stadium and the central campus area and verify current accessibility conditions in advance.

Other murals to notice at Ciudad Universitaria

O’Gorman, Siqueiros and Rivera are the essential starting point, but UNAM preserves a much wider mural collection. Works by José Chávez Morado, Francisco Eppens and other artists expand the campus narrative through themes including science, medicine, energy, cultural exchange and the relationship between humanity and nature.

If you have additional time, use UNAM’s official campus mural collection and map to locate more examples. The broader route reveals integración plástica as a campus-wide artistic program connecting many buildings and commissions.
