More than 9 hectares where Chalcatzingo Archaeological Zone, Morelos is located, were acquired by National Institute of Anthropology and History (INAH) as part of a priority project of scientific research and conservation that translates in the consolidation of this Olmeca site management program.

Formalization of the purchase took place in Morelos State Government Palace, where Jorge Morales Barud and Rafael Martinez Flores, Morelos Government secretary and sub secretary, Maria Villarreal, INAH Juridical Affairs national coordinator, and anthropologist Eduardo Lopez Calzada, Morelos INAH Center director, as well as Ejido (communal terrains) representatives, signed documentation.

Located in the municipality of Jantetelco, Chalcatzingo Archaeological Zone has a Federal Declaratory for its protection and conservation since 2002. It is at Morelos and Puebla border, an hour away from Cuernavaca and one and a half from Puebla.

“It is a little researched area that needed INAH support; this acquisition is an achievement for the Institute in matter of heritage conservation”, mentioned Eduardo Lopez Calzada.

Chalcatzingo is a Prehispanic site of Olmeca affiliation; studies reveal that first indications of human occupation go back to Early Pre Classic period (1300 BC), with settlement of agricultural groups at the foot of sacred mountains now called Acho, Delgado and Tenango.  

This area became the nucleus of the site; with the passing of time, near Medium Pre Classic period (800-300 BC), dwellers acquired knowledge that provoked ideological and cultural changes that were captured on stelae, altars, rupestrian paintings and carvings on nearby rocks.

 “We believe, according to Mesoamerican pattern, that this archaeological nucleus had civil and ceremonial functions, since it has pyramids and important buildings, among them, a ballgame court, as well as structures of socio cultural functionality”.

He added that with the aim of developing an extensive investigation about successive occupation stages, a long term management plan is to be implemented. The document is being revised to present, and after this it will be validated.  
Finally, the Morelos INAH Center considered that Chalcatzingo will have great relevance for micro regions at the orient of Morelos, because a site like this attracts many visitors and resources for communities.
