The site was an important pre-Hispanic settlement, with monumental structures built from unfired clay. It might have been an urban complex of the Classic period (300 - 900 AD) for two reasons: the layout and the monumental size of the buildings, and it is a complex in the La Mixtequilla region, which reached its peak during this period. Among the most important findings are a group of magnificent ceramic figures, including Mictlantecuhtli, the god of death. The various sculptures were accompanied by an ossuary which had one hundred clay figures, including the so-called smiling faces, and a group of women with bare torsos who have been called “Ladies of the Earth,” as they are identified with Cihuateteotl.

The culture is very similar to that of the Cerro de las Mesas site and other small Remojadas culture sites.
