TeΕtΔ«huacΔn "birthplace of the gods", or "place where gods were born." The Aztecs believed that the gods created the universe at that site.
Teotihuacan was built more than two thousand years ago, and was a flourishing city by the second century A.D. The city itself was built according to a rigorous design plan β it is laid out geometrically, and features a complex network of irrigation canals drawn from the nearby San Juan river. Though the city center, with its massive temples, is the most stunning feature of the site, a robust urban hive surrounded the ceremonial plaza. At least 2,000 dwellings have been uncovered, and the city likely housed more than 100,000 inhabitants at its peak. That would have made Teotihuacan the sixth-largest city in the world at the time.
