DVD Verdict: For those not immediately in the know, and that's OK as I wasn't sure either, Teotihuacán was an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, located in the State of Mexico 30 miles (48 km) northeast of modern-day Mexico City, known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas.

At its zenith, perhaps in the first half of the 1st millennium AD, Teotihuacan was the largest city in the pre-Columbian Americas, with a population estimated at 125,000 or more, making it at least the sixth largest city in the world during its epoch.

Apart from the pyramids, Teotihuacan is also anthropologically significant for its complex, multi-family residential compounds; the Avenue of the Dead; and the small portion of its vibrant murals that have been exceptionally well-preserved. Additionally, Teotihuacan exported fine obsidian tools that garnered high prestige and widespread utilization throughout Mesoamerica.

The city is thought to have been established around 100 BC, with major monuments continuously under construction until about 250 AD. The city may have lasted until sometime between the 7th and 8th centuries AD, but its major monuments were sacked and systematically burned around 550 AD.

Teotihuacan began as a new religious center in the Mexican Highlands around the first century AD. This city came to be the largest and most populated center in the New World. Teotihuacan was even home to multi-floor apartment compounds built to accommodate this large population. The term Teotihuacan (or Teotihuacano) is also used for the whole civilization and cultural complex associated with the site.

Here in the always-fascinating PBS series 'Secrets Of The Dead: Teotihuacán's Lost Kings' we follow a team of international scientists documenting an archeological sensation: the exploration of royal tombs beneath the ancient Mexican city of Teotihuacán. Despite many decades of research, not much is known about this long-lost society.
