The city of Teotihuacan, mysteriously abandoned some 2,000 years ago, is home to an amazing array of ancient, but largely unfathomable, structures. It’s recognized as a UNESCO World Heritage Site, in a nod to its archaeological, cultural and historical importance.
The fascinating site, located just outside Mexico City, is a famous destination thanks to how easily it can be reached, and it’s often found crawling with tourists, which is why archaeologists were amazed when it yielded a new secret in 2003 . . .
