Did You Know? (Ancient Civilizations)

The Aztecs built Tenochtitlan in the Valley of Mexico.

The Aztecs built their capital city, Tenochtitlan, on an island within Lake Texcoco in the Valley of Mexico, eventually developing it into one of the largest and most sophisticated cities in the world at the time of European contact in the early 16th century. The city's layout included an impressive network of canals, causeways, and temple complexes reflecting advanced urban planning and engineering capabilities. Following the Spanish conquest, much of Tenochtitlan was destroyed and rebuilt as the foundation of what would become modern-day Mexico City.
