Pre-Columbian Mexico in and Around Mexico City
Updated May 2026
Mexico City was built on top of Tenochtitlán, the capital of the Aztec empire, which was itself built on an island in the middle of a lake. The Spanish destroyed the Aztec buildings systematically after the conquest and used the stone to build their colonial city on top. For centuries, what lay beneath was known to exist but largely inaccessible.
It is still largely inaccessible — the colonial and modern city sits on top of it — but the picture has become considerably clearer in recent decades, and especially in the last few years. Templo Mayor in particular is in the middle of a period of discovery that is genuinely extraordinary. What follows covers the three main sites, with particular attention to what has changed since 2017.
Museo Nacional de Antropología
CHAPULTEPEC PARK — THE ESSENTIAL VISIT
The National Museum of Anthropology is the largest and most important pre-Columbian collection in Mexico, and one of the great museums of the world. Located on Reforma in Chapultepec Park, it requires a full day to do properly — two if you want to absorb the ethnographic collections on the upper floor alongside the archaeological ones below.
The ground floor moves through Mexico’s major pre-Columbian cultures: Preclassic, Teotihuacán, Toltec, Mexica (Aztec), Oaxacan (Zapotec and Mixtec), Gulf Coast, Maya, and several others. Each room is effectively its own museum. The Mexica room is the anchor — it contains the Piedra del Sol (the Aztec calendar stone, which is not actually a calendar but a cosmological diagram), the Piedra de Tizoc, and the Coatlicue, a massive goddess figure that is one of the most powerful objects in any museum I have been in.
The Olmec heads in the Gulf Coast room stop you in your tracks. The replica of Moctezuma’s feather headdress — the original is in Vienna, where it has been for five hundred years, and the repatriation conversation is ongoing — is extraordinary in scale. The Mayan tomb room requires a moment of silence.
Practical notes: arrive before 10 a.m. on weekends. The museum is free on Sundays for Mexican citizens and residents. The garden patios between rooms contain outdoor sculptures and architectural replicas — do not skip them. The on-site restaurant serves a surprisingly good breakfast, including some of the best mole I’ve had outside of Oaxaca.
Templo Mayor
CENTRO HISTÓRICO — THE LIVING EXCAVATION
Templo Mayor is the most important active archaeological site in Mexico, and arguably in Latin America. What you see when you visit — the excavated ruins of the main ceremonial complex of Tenochtitlán, right in the middle of the Centro Histórico — represents only the outermost layer of what is there. The excavation is ongoing, and the discoveries in recent years have been remarkable enough to reframe what we thought we knew about the Aztec capital.
In 2021 and 2022, archaeologists excavating beneath the existing ruins found the remains of a large circular platform — now identified as the Huei Tzompantli, the skull rack of the main temple, where thousands of sacrificial skulls were displayed. The scale of the find, and the precision of its preservation, changed the conversation about the size and ritual complexity of Tenochtitlán’s ceremonial center. More recently, the discovery of a cache of extraordinary offerings — jade figures, obsidian objects, coral, animal remains — has been dated to the reign of specific Aztec rulers, allowing archaeologists to correlate physical layers of construction with historical records in ways that were not previously possible.
The site itself is a layered archaeological cut: you walk elevated metal walkways above the ruins and look down into successive construction phases, the oldest deepest, the most recent closest to the surface. The adjacent museum houses the objects found during excavation and is one of the best archaeological museums in Mexico — dense, well-organized, and genuinely moving in the way that seeing the actual objects from a specific place always is.
Allow three hours minimum. A guide significantly enhances the visit — the INAH has official guides at the entrance, and the context they provide converts a beautiful ruin into a comprehensible civilization. The El Mayor restaurant next door has a terrace with a direct view over the site and is a good place to sit and absorb the afternoon.

If you’re interested in a guided tour of the Anthropology Museum and Templo Mayor, this one covers both.
Teotihuacán
50KM NORTHEAST — A FULL DAY OUTSIDE THE CITY
Teotihuacán was one of the largest cities in the ancient world — at its peak, between 100 and 500 CE, it had a population of perhaps 100,000 to 200,000 people, making it comparable to Rome at the same period. The builders predate the Aztecs by centuries; the Aztecs visited the site as pilgrims, as we do today, and named it Teotihuacán — “the place where the gods were created.”
What you see: the Pirámide del Sol (Pyramid of the Sun, third largest pyramid in the world by volume), the Pirámide de la Luna (Pyramid of the Moon, at the north end of the main avenue), and the Calzada de los Muertos (Avenue of the Dead) connecting them — a processional axis two kilometers long flanked by smaller temples and platforms. The Ciudadela, to the east, contains the Templo de la Serpiente Emplumada (Temple of the Feathered Serpent, also called Quetzalcóatl), which has extraordinary carved serpent heads still visible on its facade.
The archaeological understanding of the site continues to evolve. Recent research using LIDAR technology has revealed the extent of the tunnel systems beneath the pyramids — the tunnel beneath the Pyramid of the Moon in particular has yielded extraordinary objects. A 2021 discovery of a large buried platform beneath the Pyramid of the Sun has reopened questions about the original purpose and phasing of the monument.
Teotihuacán can be difficult to get to from the city if you haven’t rented a car, and the experience of floating above the pyramids and watching the sunrise is supposed to be truly spectacular. This tour has you covered if you like heights and getting up early.

A note on where to start: if you have one day and cannot choose, Templo Mayor has the advantage of being in the city center and is currently in an extraordinary moment of discovery. If you have never been to a major pre-Columbian site, Teotihuacán’s scale is the more immediately overwhelming experience. The Anthropology Museum is the essential context for everything else — it makes all other visits richer.
Which site has stayed with you longest? For me it is Templo Mayor — the idea of a civilization underneath the one I live in has never become ordinary.
