What is the magnifecent Aztec city?

The magnificent Aztec city is Tenochtitlán, founded in 1325 on an island in Lake Texcoco. It was known for its impressive architecture, including the Templo Mayor, and advanced agricultural practices, such as chinampas (floating gardens). At its height, Tenochtitlán was one of the largest cities in the world, showcasing a rich culture and complex society before the Spanish conquest in 1521. Today, its ruins lie beneath modern-day Mexico City.
