The Pyramids of Teotihuacan by Kelly Ann Pritchard

"Considered to be the site of the oldest city in Mesoamerica, the Teotihuacan pyramids are located in the state of Sonora, Mexico, and carbon testing indicates they were built anywhere from 200 B.C. To 650 BC. It is believed the original occupants left, and the site was abandoned for about 500 years until the Aztecs arrived and settled on the same land. When the Aztecs arrived the pyramids were overgrown mounts of dirt and plants, and were thought to be burial grounds of Gods."
