North of Huajuapan de León, Oaxaca, Cerro de las Minas rises above the valley that gives the modern city its setting. The archaeological zone occupies the summit and broad slopes of the hill, now surrounded in part by urban neighborhoods. It is not a remote monumental complex with a fully documented visitor circuit; it is an archaeological landscape embedded in a living city, where ancient remains and contemporary streets meet.
Archaeologists associate the site with the Ñuiñe cultural tradition of the Mixteca Baja, the hot lowland region spanning parts of Oaxaca, Puebla and Guerrero. The earliest archaeological evidence identified so far dates to about 400 BCE. Research summarized by Mexico’s National Institute of Anthropology and History estimates an occupation of roughly a millennium. Those are archaeological ranges, not a claim that the same political order or population remained unchanged throughout that time.
