It is a mixed plan structure, that is, the main body is circular in shape and the rectangular façade with lateral alfardas that support the access stairway, which is oriented to the east. During the explorations from 1964 to 1968, more than 200 bodies of sacrificed subjects were found on the access platform. They also found remains of laminated wood, tejamanil, which was placed on top of the whole complex to later lay the new floor with which the great ceremonial complex was sealed, as well as painted gourds and human remains with evidence of decapitation, mutilations and cremation of immolated beings so that Ehecatl would put an end to the evils that devastated the Mexica people.

Between 1987 and 1989 an excavation was carried out along the land in front of the main platform and 41 burials and 54 offerings were discovered, including infants inside pots with ceramic figurines, as well as stone, shell, wood, among other objects. This set was offered to the god of the wind, Ehécatl-Quetzalcóatl, to request his intervention during the drought that devastated the population between 1454 and 1458.
