"

Chicoloapan is the site of an unprotected ancient Mesoamerican city of the same name. The first settlements in the area were before the rise of Teotihuacan around 200 BCE, and it prospered for generations after the fall of Teotihuacan around 550-600 CE.[1] The site's long history of settlement provides important insight into the relationship between urban centers and their hinterlands.
