Tourists walking around the Teotihuacan in Mexico

Teotihuacan was an ancient Mesoamerican city that was established around 100 BC. At one time, it was the largest metropolis in the pre-Columbian Americas and had significant cultural influence on surrounding areas. The Aztecs named the region Teotihuacan (“the place where gods were created”) when they arrived centuries after its fall. Here, you can walk along the Avenue of the Dead, Teotihuacan’s main road. The broad, central thoroughfare dissects the city and is surrounded by mounds that resemble large tombs. Tourists can view a number of well-preserved murals, as well as the Pyramid of the Moon and the Pyramid of the Sun. The latter is the third largest pyramid in the world. Teotihuacan became a UNESCO World Heritage Site in 1987.
