It extends in the middle of an open space and had to do, most probably, with the rites that took place in its two altars. The first one, rectangular in shape, was found destroyed by looting. The second, circular, offered interesting evidence, since a total of 19 burials were recovered from its interior and six from its exterior. It is undoubtedly that the ceremonial spaces were fundamental for the social organization, because in them acts and rites were carried out where the gods legitimized the authority of the priests and the governing elites.

Structure 3 or Circular Altar: It is built in honor of Ehecatl. It is an element with a greater symbolism, because in it was carried out the deposition of human remains as a cemetery; however, they were not buried in a common way for its time, because instead of burying the body in a flexed or seated way, wrapped in a funeral bundle, these individuals were cremated so in their remains there were clear traces of having gone through high temperatures, between 300°C to 900°C.

Due to their location inside the architectural element and the way in which the bodies were prepared, it can be inferred that these were very important people for society, such as priests, high-ranking figures or ball players, who were assigned a dignified place where they could be venerated.
