A military fortress built on the upper part of a hill, flanked on three sides by precipitous ravines. Distinguished by its formidable surrounding stone wall. Administrative center of one the most important Popoloca domaines (1200-1500 AD), with monumental architecture.

Conquered by the Mexica in the fifteenth century, this site served as a garrison and point of communication with the powerful Itzocan kingdom, on the route to the Mixteca region. The archeological zone occupies a small area, with traces of platforms beneath some nearby houses. A Calvary chapel was constructed over the principal building in the seventeenth century, and parts of these walls remain.

This is the most important pre-Hispanic settlement of those explored so far in the state of Puebla, and one of the main sites in Mexico. Its attractions include the Great Pyramid and the plaza known as the “courtyard of altars.”

According to Justo Sierra, the ancient Mexicans were people of corn. This plant of humble origins was domesticated and greatly improved over the course of a long and astonishing social and biological history, as set out in this museum, together with the ancient figures of pre-Hispanic gods.

A modern building houses a vast collection about the life and culture of the state. Archeology, history (in the nineteenth century Puebla was laid siege ten times), academic culture, popular culture, customs, dances and a great variety of arts and crafts.
