There are an estimated 200,000 archaeological sites in Mexico – among them, the Mayan ruins and pyramids in the country’s south, the Paquime mud-based constructions in the northern state of Chihuahua and the huge complex of Teotihuacan, north of Mexico City.
Teotihuacan is probably the best known archaeological site in Mexico
The government admits that just 40,000 archaeological sites are properly registered; of those, only 160 are supervised and open to the public.
Most sites are unsupervised, with many located on private property or in remote locations. They are vulnerable to those who illegally extract artefacts to sell on, sometimes for thousands of dollars.
