Teotihuacan
The ancient Mesoamerican city of Teotihuacan is located about an hour's drive north of Mexico City. Once boasting a population of approximately 125,000, Teotihuacan was once one of the largest cities in the world, at a time when its existence was not known to most of the planet's inhabitants. The archaeological site includes the ruins of two major pyramids, numerous ceremonial platforms, and the ruins of residences and temples. The city is thought to have existed in its prime between around 100 BC-550 AD. By the time the Aztecs found it, it was already in ruins – and much of what is known about Teotihuacan, including its name, comes from the Aztecs, not those people who originally built it. Today the site exists as one of the largest and most important anciety Mesoamerican archaelogical sites, offering visitors easy access to climb the two pyramids, view remarkably well preserved paintings, and an excellent museum that houses many of the smaller artifacts found here.
