Which pre-Columbian civilization is famous for having built the city-state of Tenochtitlán, on which Mexico City is now built?

The Aztecs

Founded in 1325, Tenochtitlán was the capital of the Aztec empire and represented a masterpiece of engineering and architecture, with its majestic temples, palaces, and canals. Located on an island in the middle of Lake Texcoco, the city was connected to the mainland by three large causeways. The sophistication and beauty of Tenochtitlán amazed the Spaniards upon their arrival, although they ultimately led to its destruction in their quest for conquest. Today, Mexico City stands on the ruins of this legendary city, bearing witness to the profound legacy of the Aztecs.
