Tenayuca
First capital of the Chichimecas of Xólotl (end of the twelfth century) until it was moved to Texcoco. It still contains an extraordinary pyramid crowned with twin temples dedicated to Tlaloc and Huitzilopochtli, with glyphs on many steps and surrounded by a wall of serpents.
The foundation of Tenayuca is attributed to the Chichimec group led by Xólotl in the year 1250. Later, after the Chichimec capital moved to Texcoco, Tenayuca became part of the Tepaneca dominion of Azcapotzalco. Then, in the final part of its pre-Hispanic history, it was closely tied to the Mexica of Tenochtitlan, until the arrival of the Spanish.
Its location on the shore of Lake Texcoco meant its inhabitants had the raw materials to produce salt, whilst the Tlalnepantla and San Javier rivers supplied them with vegetables and fish, as well as sufficient water for farming. Finally, they extracted the stone to build their monuments and homes from the Cerro de Tenayo and other peaks in the Sierra de Guadalupe.
One of the most outstanding characteristics of Tenayuca is its majestic monument surrounded by sculptures of serpents. These may be seen not only on the four sections of the pyramid, but also the base it stands upon. In Bernal Díaz del Castillo's eyewitness account, the True History of the Conquest of New Spain, he notes that on their first journey to Mexico, the Spanish soldiers called Tenayuca the "Town of Serpents." The temple would undoubtedly have caused astonishment, as it is calculated that in its final stage of construction—the one the conquistadors encountered—there were approximately 600 serpent heads embedded in the Great Temple monument. If we add the 140 serpents whose bodies lie on the platform of the Coatepantli, their astonishment must have been all the greater.

Altares de la Xiuhcóatl
Separated from the Great Temple, on the north and south sides, there are small altars (two on the north and one on the south). Their peculiarity lies in the fact that they are associated with figures identified as Xiuhcoatl (fire serpent).
Separated from the Great Temple, on the north and south sides, there are small altars (two on the north and one on the south). Their peculiarity lies in the fact that they are associated with figures identified as Xiuhcoatl (fire serpent). The heads of the reptiles are carved in stone and emerge from a coiled body of masonry. They accentuate the details of the fangs and emphasize the crest in the form of a volute topped with protuberances. The altars of the Xiuhcoatl correspond to the type of platforms defined as momoztli, that is, small temples located at the foot of or associated with the main temple where ceremonies were held or offerings were placed.

Templo Mayor de Tenayuca
It is the most important monument of the site. This pyramidal base of staggered bodies is characteristic of the religious architecture of the Late Postclassic (1200-1521).
It is the most important monument of the site. This pyramidal base of staggered bodies is characteristic of the religious architecture of the Late Postclassic (1200-1521). As in other buildings of its type, the two main deities were worshipped here: Tlaloc, god of rain and maintenance, and Huitzilopochtli, god of war. The temple was enlarged seven times. The oldest took place around 1250, and the last, between 1450 and 1500. Undoubtedly the Templo Mayor de Tenayuca is the most complete of those preserved in central Mexico, and where the religious and artistic expressions of the Nahua people are still preserved.

Altar de los Cráneos o de las Calaveras
In front of the main temple, on the platform where the stairs are raised, there is a small rectangular altar, also added in the last constructive stage. In three of its sides it has embedded sculptures of skulls and quadrets with the representation of crossed bones.

In three of its sides it has embedded sculptures of skulls and quadrets with the representation of crossed bones. The researcher Alfonso Caso described this altar as the tomb of the solar god. In the interior there was a painting with the same motifs, whose remains were removed to stop the deterioration. However, in the site museum of the archaeological zone, called Xólotl, a reproduction of that painting can be seen today.

Coatepantli
During the last construction stage of the Great Temple, the north, south and east sides were enriched with the platform of the Coatepantli (serpent wall). The bodies of the reptiles, formed with stones and a mortar of lime and mud, were designed with curvatures to appear to be in movement.

The bodies of the reptiles, formed with stones and a mortar of lime and mud, were designed with curvatures to appear to be in movement. In the heads, carved in stone, the fangs, the slit eyes and the forked tongue of the reptiles can be appreciated. Another realistic feature is observed in three small steps that top the body simulating the ring or rattle characteristic of the Crotalus triseriatus (rattlesnake). If you look closely, in some specimens there are still traces of the colors (red, blue, black and green) that covered the bodies.
