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.

It owes its name to the petroglyphs carved in the niches of its secondary facades, which represent the count of the days, ordered by thirtieths, corresponding to the ritual calendar or Tonalpohualli. In 1989, in the center of the main façade, a mural painting was discovered representing the time-creating couple, Cipactónal and Oxomoco. This one contains the 13 days of the fourth trecena, which, together with the other three facades, forms the total representation of 52 days, perhaps manifesting the count of the 52 years that made up a Mexica century or Xiuhmolpilli.

The investigation of the temple, its mural paintings and the associated offerings allow us to propose that it was used by the Mexica priest called Tonalpouhque, who had the knowledge of the sacred books and who could determine the name of the newborns from the gifts of the gods that governed the year, the month and the day thanks to the Tonalpohualli.

It is a complex composed of four small rooms and a central courtyard with an altar attached to the north wall. Remains of the pilasters that formed a wide portal are also preserved, as well as two access stairways, divided by a central dado decorated with tezontle nails.

Its architecture presents the model of talud-tablero of Teotihuacan influence, identical to the “red temples” of the archaeological zone of the Templo Mayor of Tenochtitlan. Its platform is higher than the steps of the staircase of the main façade, which is oriented to the east. The three remaining facades are decorated with reliefs that represent banners as bows and remains of the mural painting that decorated the facades, boards and alfardas are preserved. Apparently, this building was dedicated to Xochipilli. To the south is Temple X with the same orientation and a wider façade, unfortunately we have no information about its original use.

This building is identical in size, orientation and architecture to the Templo Mayor of Tenayuca and Tenochtitlan, which in its same stage preserves part of the shrines dedicated to Tlaloc and Huitzilopochtli. The name is due to the fact that it is the main temple within the Mexica ceremonial precinct. It was dedicated to Huitzilopochtli, whose shrine was located in the southern half of the building, and to Tlaloc, who was worshiped in the northern half.

The Great Temple of Tlatelolco was built from a platform from which four staggered and superimposed pyramidal bodies were deployed, on top of which stood the shrines of each deity. In the lateral and back facades of the building a series of glyphs carved in stone can be appreciated, one hundred decorating the side of Huitzilopochtli and fifty that of Tláloc. Like the Templo Mayor of Tenochtitlan, the Tlatelolco Temple has seven complete construction stages and two extensions of its main facade, as evidenced by the stairways distributed one after another and oriented to the west.

Also known as Gran Basamento, it is located northwest of the Templo Mayor Tlatelolca. It is a rectangular building built entirely with pink quarry, unlike the rest of the buildings in the area. Temple I was discovered in 1962 by archaeologist Francisco Gonzalez Rul, who was unable to explore its interior, and was subsequently excavated between 2007 and 2009, when remains of a possible earlier construction stage and more than a hundred burials belonging to a later time, clearly arranged, were detected. The location and architecture of the Great Basement suggest that it may have been dedicated to the Tlatelolca military elite, like the House of the Eagles in Tenochtitlan.
