Tenochtitlan exists today as the historic center of Mexico City, with its ruins preserved within the UNESCO World Heritage Site of Templo Mayor and Xochimilco’s floating gardens.
Is Tenochtitlan still there?
Yes, Tenochtitlan’s ruins remain in Mexico City’s historic center, particularly at the Templo Mayor archaeological site and the canals of Xochimilco.
You’ll find the city’s foundations buried beneath the modern streets, while ongoing digs keep uncovering temples, palaces, and Aztec-era artifacts. The UNESCO World Heritage Site of Xochimilco also keeps alive parts of Tenochtitlan’s original lake-based layout, complete with chinampas (those famous floating gardens).

Are Teotihuacan and Tenochtitlan the same?
No, Teotihuacan and Tenochtitlan are distinct cities separated by over 500 years in history and culture.
Teotihuacan—often called the "City of the Gods"—peaked between 100 BCE and 650 CE, long before the Aztecs showed up. Tenochtitlan, founded in 1325 CE, became the Aztec powerhouse. Both sit in central Mexico, but their vibes? Totally different. Teotihuacan’s colossal pyramids (hello, Sun and Moon) weren’t built by the Aztecs at all. In fact, the Aztecs later treated Teotihuacan as a sacred place and slapped that name on it. For a side-by-side look, National Geographic has some great visuals.
Is Mexico City built over a lake?
Partially, Mexico City occupies the drained basin of Lake Texcoco, which once surrounded Tenochtitlan.
Most of the lake got drained by the Spanish back in the 1600s, but the city’s spongy, clay-heavy ground still holds water—and that’s why parts of it sink unevenly. The historic center, including the Zócalo, sits right on the old lakebed. Today, engineers wrestle with water extraction and conservation to slow the sinking. For the gritty details, Scientific American digs into the mess.
Was Tenochtitlan the largest city in the world?
At its peak in 1519, Tenochtitlan had an estimated 200,000 inhabitants, making it one of the largest cities globally at the time.
Spanish conquistador Hernán Cortés and others described it as bigger than European hotspots like London or Seville. The city’s grid design, aqueducts, and massive markets (Tlatelolco was a beast) left Europeans stunned. Want numbers? Britannica compares Tenochtitlan’s population to other pre-Columbian cities.
What caused the fall of Teotihuacan?
Scholars attribute Teotihuacan’s collapse (c. 600 CE) to internal unrest, including the destruction of elite buildings and artifacts.
Some think a peasant revolt or a brutal power struggle did it in. Unlike later Maya or Aztec declines, Teotihuacan shows no signs of invasion or drought. Its fall remains one of Mesoamerica’s biggest unsolved mysteries. For the wildest theories, Smithsonian Magazine lays out the possibilities.
Who really built Teotihuacan?
The builders of Teotihuacan remain unidentified, though the city predates the Aztecs by nearly a thousand years.
No single ethnic group has been pinned down as the architects. The Aztecs, who rolled in during the 1300s, called the ruins Teotihuacan ("Birthplace of the Gods") and treated its pyramids as holy ground. Modern archaeology suggests the city was more of a melting pot. The Archaeological Institute of America sums up the debate.
Is it safe to visit Teotihuacan?
Yes, Teotihuacan is safe for visitors as of 2026, with standard precautions advised for archaeological sites.
The site gets regular patrols by Mexican federal police, and guided tours are a smart way to explore safely. Skip the off-limits climbing zones and leave the bling at home. For real traveler insights, the TripAdvisor Teotihuacan page has safety tips and reviews.
Is Mexico City sinking?
Yes, parts of Mexico City sink up to 20 inches (50 cm) annually due to groundwater extraction and clay soil.
Since the early 1900s, some areas have dropped over 30 feet (9 meters), warping roads and cracking buildings—even the Metro system isn’t immune. Solutions? Rainwater collection and tighter rules on water wells. The New York Times has the sobering scoop.
What do most Mexicans call Mexico City?
As of 2026, Mexico City is officially known as Ciudad de México (CDMX).
The name switch from "Distrito Federal" (DF) to CDMX happened in 2016, marking its status as a full federal entity. Locals toss around "CDMX" in formal settings and "Mexico City" casually. For official updates, the CDMX government website is the place to go.
Why is Mexico City so high?
Mexico City’s elevation (7,350 feet/2,240 meters) stems from its location in the Valley of Mexico, surrounded by mountains.
The valley’s lofty perch and mild climate made it a magnet for settlers. The Aztecs picked this spot for its natural defenses and easy access to Lake Texcoco. Today, the altitude can leave visitors gasping—literally. Britannica breaks down the geography.
Who destroyed Tenochtitlan?
The Spanish, led by Hernán Cortés, destroyed Tenochtitlan in 1521 after a 93-day siege.
The collapse wasn’t just military—indigenous allies (shoutout to the Tlaxcala) and a smallpox outbreak, brought by the Europeans, sealed the city’s fate. Cortés ordered the ruins torn down and Mexico City built on top. For the full story, the History Channel has the play-by-play.
What is Tenochtitlan called today and why?
Tenochtitlan is called Mexico City because the Spanish renamed it after conquering the Aztec capital in 1521.
The name "Mexico" comes from the Aztecs’ own word, "Mēxihco," which referred to their homeland. Modern Mexico City sits on the exact same ground. The National Geographic traces the name’s journey.
What was the original name of the Aztecs?
The Aztecs originally called themselves the Mexica (or Tenochca).
Those names tie back to their mythical origins in Aztlán and their capital, Tenochtitlan. The term "Aztec" was actually a later European label for the Mexica and their allies. The Encyclopaedia Britannica clears up the naming confusion.
What do you wear to Teotihuacan?
Wear lightweight, breathable clothing, sturdy shoes, sunscreen, and a hat for a visit to Teotihuacan.
You’ll be climbing pyramids, so comfy shoes are a must. Layer up—temperatures shift fast. Pack water, sunscreen, and a camera; shade is scarce. If you can swing it, weekdays mean fewer crowds. The Lonely Planet guide has more packing hacks.
Why are the Mayans called the Mayans?
The term "Mayan" refers to the Maya people’s linguistic and cultural unity, though they identify by specific ethnic groups (e.g., Yucatec, K’iche’).
The name comes from the Post-Classic city of Mayapán in the Yucatán. Unlike the Aztecs, the Maya never formed one big empire but shared languages and traditions across southern Mexico and Central America. The National Geographic dives into their rich diversity.
