The city of Tenochtitlan is the capital of the Mexicas' life; this building is the most important and also a sacred place. It served as a place of worship for their main deities, to whom the temples crowning the pyramid are dedicated: Huitzilopochtli (south), the god of war; and Tláloc (north), the god of rain. It reached an approximate height of 45 meters, being the largest. It dates back to seven construction stages. Its location combines the four cardinal points, and it is also believed to represent the different levels of the cosmos.

In Mexica culture, jaguars, along with eagles, were the two most important military orders among the Mexica. The jaguar was associated with being a predator of the underworld and darkness, while the eagle was seen as a celestial predator. Jaguar warriors belonged to the lower class, and eagle warriors were from the nobility. The jaguar military order wore attire resembling this animal because they believed it would imbue them with its strength in battle.

Tezcatlipoca, the Smoking Mirror, was the one who bestowed goods or withheld them and could bring misfortune as well. He brought an end to the golden age of the Toltecas and led Quetzalcoatl astray. He is depicted with a black stripe across his face and an obsidian mirror in place of one of his feet or on his chest, with which he could see all human actions and thoughts, emitting smoke that killed his enemies. In May, the festival of Toxcatl was dedicated to him, during which a warrior was offered to him. It was during this celebration in 1520 that Pedro de Alvarado led a massacre.

According to Mexica mythology, Tonatiuh represents the cosmic era in which the Mexica people lived, as told in the legend of the Five Suns. After the disappearance of the Fourth Sun, Tonatiuh ruled the universe as the Fifth Sun, with the first being the god Tezcatlipoca, the second Quetzalcoatl, the third Tlaloc, and the fourth the goddess Chalchiuhtlicue. This is the temple of Tonatiuh, the god of the sun. Due to its main front facing east, it is also known as the Temple of the Rising Sun. Nowadays, it is located beneath the Metropolitan Cathedral.

The Chalchihuitl figure was distinguished as one of the most important symbols of fertility, and it was often associated with the sun as well.

Ehecatl, the god of wind, is one of the main deities in Mexica culture, associated with the creation of the Fifth Sun, helping it stay in motion. He is considered a manifestation of Quetzalcoatl. Priests would enter this temple through a snake-shaped door, where they would invoke Ehecatl for mercy and the continuous and gentle flow of air, enabling canoes to move through the city.

Till date, is not known with certainty to which deity this temple was dedicated to, but there is a possibility that it was the Coateocalli, the House of the Snake, where the deities of the peoples conquered by the Mexica were often kept. This was the first archaeological window that was discovered. In it, a sculpture of Xiuhcoatl, the Fire Serpent, was found, followed by one of Ocelotl Cuauhxicalli with representations of Huitzilopochtli and Tezcatlipoca.

It represents a sacred mountain and measures approximately 40 meters in width from north to south. It provides evidence that it was constructed in five stages spanning the period from 1440 to 1521.

Eagles represented celestial predators, and the eagle warriors belonged to the noble Mexica military order. These warriors were considered the bravest and were distinguished by their eagle attire, which was believed to imbue them with special qualities. Inside this enclosure, remnants of blood, vegetable and animal fats, as well as what appears to be pulque residue, were found. This indicates that it was a space consecrated for offerings and ceremonies to the gods, as well as for the enthronement of the new Huey Tlatoani. Here, the tlatoani would perform a ritual in which he exited through the west door to follow the path toward the Sun, and then the vestibule led him to the north door, where figures of Mictlantecuhtli are located, ultimately leading to the Mictlan. It was constructed and expanded in three stages between 1430 and 1500.
