Teotihuacan - The City of the Gods

Teotihuacan means 'The City of the Gods", or "Where Men Become Gods"(in Nahuatl). It is located in the valley of the same name 30Teotihuacan used to be a thriving city and ceremonial center that predated the Aztecs by several centuries. Most likely it was Mexico's biggest ancient city at its peak and the sixth largest city in the world in AD 600.
Teotihuacan began declining sharply around 650 AD, and was almost completely abandoned around 750 AD. No one knows why?

At its peak around 500-600 A.D., Teotihuacan contained perhaps 200,000 people. It was a well planned city covering nearly eight square miles and larger and more advanced than any European city of the time. Its civilization was contemporary with that of ancient Rome , and lasted longer - more than 500 years.

Though archaeologists have long been fascinated with the site, Teotihuacan's culture and history are still largely mysterious. The civilization left massive ruins, but no trace has yet been found of a writing system and very little is known for sure about its inhabitants, who were succeeded first by the Toltecs and then by the Aztecs. The Aztecs did not live in the city, but gave the place and its major structures their current names. They considered it the "Place of the Gods" - a place where, they believed, the current world was created
