Ciudad Universitaria (C.U.)
A working university built on a volcano's lava field — and wrapped in the world's largest mural.

UNAM's main campus covers 1,000 hectares of solidified lava deposited by the Xitle volcano around 100 AD. Completed in 1954 and declared a UNESCO World Heritage Site in 2007, its concentric roads, volcanic-rock walls, and open gardens replace any conventional campus grid. Sunday afternoons bring families out to the footpaths — the whole place doubles as a public park.
What to look for
- Juan O'Gorman's mural on the Central Library — it covers all four sides of the building and is recognized as the largest mural in the world
- David Alfaro Siqueiros's mural on the Rectorate Tower, the tall square building set deliberately apart from the rest of campus
- Volcanic rock from the original lava bed reused in place — look at the pathways and outer walls throughout the grounds
Open campus, no entry fee; buildings require a 5–10-minute walk from the main roads, so wear comfortable shoes.
