Located 30 miles outside Mexico City, Teotihuacan was the largest city in the Western Hemisphere prior to 1450. During its golden age, Teotihuacan covered 8 square miles and supported a population over 100,000. It is renowned for its immense causeway and pyramids— notably the Temples of the Moon and the Sun— which are comparable in size to the largest in Egypt. The Aztec Empire, which came to control Teotihuacan nearly 1000 years later, was as awestruck by it then as students are today.
