Drawing of what part of Tenochtitlan may have looked like

Tenochtitlan was the capital city of the Aztec Empire. The Aztecs built Tenochtitlan around 1325, right on a lake called Lake Texcoco.

As the Empire grew, so did Tenochtitlan. By the early 1500s, at least 200,000 people lived in the city. This made Tenochtitlan the largest city in the Americas before Christopher Columbus arrived.
