Uncovering the Secrets of Mexico’s Mysterious Ancient City
Just 50 kilometers northeast of Mexico City lies one of the most extraordinary and mysterious archaeological sites in the world: Teotihuacán. A UNESCO World Heritage Site, this sprawling ancient city was once a cultural, spiritual, and economic powerhouse, one of the largest cities in the ancient world. Here we give you 10 facts about Teotihuacán.
Despite its massive pyramids and impressive urban planning, much about Teotihuacán remains a mystery. Who built it? Why was it abandoned? How did it become such an influential force in Mesoamerican history?
Top 10 Fascinating Facts
1. Nobody Knows Who Built It
Unlike cities tied to well-documented empires like the Maya or Aztecs, Teotihuacán’s origins remain unclear. The city predates the Aztec Empire by nearly 1,000 years. In fact, when the Aztecs arrived in the region, the city had already been abandoned for centuries. They were so awed by its size and beauty that they named it Teotihuacán, meaning “The place where the gods were created.”
Scholars speculate that Teotihuacán may have been built by a multiethnic group, possibly including the Totonacs, Otomi, or Nahua peoples.
2. One of the Largest Cities in the Ancient World
At its peak around 500 CE, Teotihuacán was home to over 100,000 residents, making it one of the largest cities in the world at the time. It covered more than 20 square kilometers (8 square miles) and featured vast residential zones, temples, markets, and ceremonial plazas.
Its scale is comparable to ancient Rome or Chang’an (modern-day Xi’an, China), marking it as a major center of civilization.

3. The Avenue of the Dead Is Misnamed
The main road that cuts through Teotihuacán know as the Avenue of the Dead (“Calzada de los Muertos”). Early archaeologists believed the mounds along the avenue were tombs. However, later research revealed they were actually platforms for temples and palaces.
The name stuck, but the truth paints a very different picture: this was the city’s grand ceremonial boulevard, connecting major sites like the Pyramid of the Moon, Pyramid of the Sun, and the Citadel.
4. The Name Means “The Place Where the Gods Were Created”
“Teotihuacán” is a Nahuatl word (the language of the Aztecs), and reflects the awe the Mexica felt when they discovered the ruins. They believed the city was a sacred site where gods sacrificed themselves to create the sun and the moon, a cornerstone myth of Mesoamerican cosmology.
6. It Was a Multicultural Metropolis
Evidence from murals, pottery, and architecture suggests that Teotihuacán was a multiethnic and multicultural society. Distinct neighborhoods housed people from distant regions, including the Zapotecs, Maya, and Mixtecs.
This diversity likely contributed to its strength as a trade and religious hub, influencing cultures across Mesoamerica.

5. Home to the Third-Largest Pyramid in the World
The Pyramid of the Sun stands as the crown jewel of Teotihuacán. At 65 meters (213 feet) tall and 225 meters (738 feet) wide, it’s one of the largest pyramids on Earth. Only the Great Pyramid of Cholula (Mexico) and the Great Pyramid of Giza (Egypt) surpass it in volume.
Although climbing the pyramids is currently prohibited for preservation reasons, observing their majesty and walking around the surrounding squares still offers visitors a unique experience. The sheer scale and symmetry of these structures continue to captivate visitors from around the world.
7. Advanced Urban Planning
Teotihuacán is a marvel of urban design. Its streets was aligned with celestial and astronomical precision. Engineers built a complex grid system, complete with multi-family housing compounds, drainage canals, and wide plazas.
This high level of organization suggests an advanced centralized government and sophisticated knowledge of engineering and astronomy.
8. Human and Animal Sacrifices Were Practiced
Archaeologists have discovered evidence of ritual sacrifices in and around the pyramids. Human and animal remains, often adorned with ceremonial objects, were buried during the construction of major structures.
These sacrifices were likely intended to consecrate the buildings and honor the gods, reflecting a deeply spiritual worldview.

9. Teotihuacán Influenced Other Civilizations
Even after its fall around 550 CE, Teotihuacán’s influence rippled throughout Mesoamerica. The Maya and later the Aztecs adpted its architectural style, religious symbols, and urban planning.
Cities like Tikal and Copán in the Maya region show clear signs of Teotihuacán influence, and Aztec rulers often made pilgrimages to the site.
10. It Remains Full of Mysteries
Despite decades of excavation, Teotihuacán still holds many secrets. The cause of its collapse is unknown, some believe internal uprisings, environmental shifts, or resource depletion may have played a role.
Tunnels beneath the Pyramid of the Feathered Serpent were only discovered in recent years, and new discoveries continue to emerge, suggesting we’ve only scratched the surface of what Teotihuacán once was.
