The Templo Mayor (“Main Temple”) was one of the main temples of the Aztecs in their capital city of Tenochtitlan, which is now Mexico City.
Its architectural style belongs to the late Postclassic period of Mesoamerica. The temple was called the Huēyi Teōcalli in the Nahuatl language and dedicated simultaneously to two gods, Huitzilopochtli, god of war, and Tlaloc, god of rain and agriculture, each of which had a shrine at the top of the pyramid with separate staircases.
The spire in the center of the adjacent image was devoted to Quetzalcoatl in his form as the wind god, Ehecatl. The Great Temple devoted to Huitzilopochtli and Tlaloc, measuring approximately 100 by 80 m (328 by 262 ft) at its base, dominated the Sacred Precinct.
Construction of the first temple began sometime after 1325, and it was rebuilt six times. The temple was destroyed by the Spanish in 1521 to make way for the new cathedral.
The site is part of the Historic Center of Mexico City, which was added to the UNESCO World Heritage List in 1987.
After the destruction of Tenochtitlan, the Templo Mayor, like most of the rest of the city, was taken apart and covered over by the new Spanish colonial city. The Temple’s exact location was forgotten, although by the 20th-century scholars had a good idea where to look for it. This was based on the archeological work done at the end of the 19th century and the first half of the 20th.
Leopoldo Batres did some excavation work at the end of the 19th century under the Mexico City Metropolitan Cathedral because at this time, the temple was thought to be there. In the first decades of the 20th century, Manuel Gamio found part of the southwest corner of the temple and his finds were put on public display.
However, it did not generate great public interest in excavating further because the zone was an upper-class residential area. In 1933, Emilio Cuevas found part of a staircase and beam. In 1948, Hugo Moedano and Elma Estrada Balmori excavated a platform containing serpent heads and offerings. In 1966, Eduardo Contreras and Jorge Angula excavated a chest containing offerings that was first explored by Gamio.
The push to fully excavate the site did not come until late in the 20th century.
On 21 February 1978, workers for the electric company were digging at a place in the city then popularly known as the “island of the dogs”. It was so named because it was slightly elevated over the rest of the neighborhood, and when that was flooded, street dogs would congregate there. Just over two meters down, the diggers struck a pre-Hispanic monolith. This stone turned out to be a huge disk of over 3.25 meters (10.7 feet) in diameter, 30 centimeters (11.8 inches) thick and weighing 8.5 metric tons (8.4 long tons; 9.4 short tons). The relief on the stone was later determined to be Coyolxauhqui, Huitzilopochtli’s sister, dating to the end of the 15th century.
From 1978 to 1982, specialists directed by archeologist Eduardo Matos Moctezuma worked on the project to excavate the Temple. Initial excavations found that many of the artifacts were in good enough condition to study. Efforts coalesced into the Templo Mayor Project, which was authorized by presidential decree.
To excavate, 13 buildings in this area had to be demolished. Nine of these were built in the 1930s and four dated from the 19th century, and had preserved colonial elements. During excavations, more than 7,000 objects were found, mostly offerings including effigies, clay pots in the image of Tlaloc, skeletons of turtles, frogs, crocodiles, and fish, snail shells, coral, some gold, alabaster, Mixtec figurines, ceramic urns from Veracruz, masks from what is now Guerrero state, copper rattles, decorated skulls and knives of obsidian and flint. These objects are housed in the Templo Mayor Museum. This museum is the result of the work done since the early 1980s to rescue, preserve and research the Templo Mayor, its Sacred Precinct and all objects associated with it. The museum exists to make all of the finds available to the public.
The excavated site consists of two parts: the temple itself, exposed and labeled to show its various stages of development, along with some other associated buildings, and the museum, built to house the smaller and more fragile objects.
Mexican pyramids were typically expanded by building over prior ones, using the bulk of the former as a base for the latter, as later rulers sought to expand the temple to reflect the growing greatness of the city of Tenochtitlan. Therefore, digging down through this pyramid takes us back in time. The first temple was begun by the Aztecs the year after they founded the city, and the pyramid was rebuilt six times. All seven stages of the Templo Mayor, except the first, have been excavated and assigned to the reigns of the emperors who were responsible for them.
Construction of the first Templo Mayor began sometime after 1325. This first pyramid is only known through historical records, because the high water table of the old lakebed prevents excavation. According to these records, the first pyramid was built with earth and perishable wood, which may not have survived to the present time.
The second temple was built during the reigns of Acamapichtli, Huitzilihuitl and Chimalpopoca between 1375 and 1427. The upper part of this temple has been excavated, exposing two stone shrines covered in stucco on the north side. A chacmool was uncovered as well. On the south side, there is a sacrificial stone called a “téchcatl” and a sculpted face.
The third temple was built between 1427 and 1440 during the reign of Itzcoatl. A staircase with eight stone standard-bearers is from this stage bearing the glyph with the year Four-Reed (1431) These standard bearers act as “divine warriors” guarding the access to the upper shrines.
The fourth temple was constructed between 1440 and 1481 during the reigns of Moctezuma I and Axayacatl. This stage is considered to have the richest of the architectural decorations as well as sculptures. Most offerings from the excavations are from this time. The great platform was decorated with serpents and braziers, some of which are in the form of monkeys and some in the form of Tlaloc. At this time, the stairway to the shrine of Tlaloc was defined by a pair of undulating serpents and in the middle of this shrine was a small altar defined by a pair of sculpted frogs. The circular monolith of Coyolxauhqui also dates from this time.
The fifth temple (1481–1486) is dated during the short reign of Tizoc. During these five years, the platform was recovered in stucco and the ceremonial plaza was paved.
The sixth temple was built during the reign of Ahuizotl. He finished some of the updates made by Tizoc and made his own; as shown on the carvings of the “commemoration stone of the huei teocalli”, showing the two tlatoqueh celebrating the opening of the temple during the last day of the month Panquetzaliztli dedicated to Huitzilopochtli; day 7 acatl of the year 8 acatl (Dec 19th, 1487). The Sacred Precinct was walled off and this wall was decorated with serpent heads. He built three shrines and the House of the Eagle Warriors.
The seventh and last temple is what Hernán Cortés and his men saw when they arrived to Tenochtitlan in 1519. Very little of this layer remains because of the destruction the Spaniards wrought when they conquered the city. Only a platform to the north and a section of paving in the courtyard on the south side can still be seen.
Most of what is known about this temple is based on the historical record. It was at the time the largest and most important active ceremonial center. Fray Bernardino de Sahagún reported that the Sacred Precinct had 78 buildings; the Templo Mayor towered above all of them.
The pyramid was composed of four sloped terraces with a passage between each level, topped by a great platform that measured approximately 80 by 100 meters (262 by 328 feet). It had two stairways to access the two shrines on the top platform. One was dedicated to Tlaloc, the god of water on the left side (as you face the structure), and one to Huitzilopochtli, deity of war and of the sun, on the right side. The two temples were approximately 60 meters (200 feet) in height, and each had large braziers where the sacred fires continuously burned. The entrance of each temple had statues of robust and seated men which supported the standard-bearers and banners of handmade bark paper. Each stairway was defined by balustrades flanking the stairs terminating in menacing serpent heads at the base. These stairways were used only by the priests and sacrificial victims. The entire building was originally covered with stucco and polychrome paint.
The deities were housed inside the temple, shielded from the outside by curtains. The idol of Huitzilopochtli was modeled from amaranth seeds held together with honey and human blood. Inside of him were bags containing jade, bones and amulets to give life to the god. This figure was constructed annually and it was richly dressed and fitted with a mask of gold for his festival held during the Aztec month of Panquetzaliztli. At the end of the festival, the image was broken apart and shared among the populace to be eaten.
In his description of the city, Cortés records that he and the other Spaniards were impressed by the number and magnificence of the temples constructed in Tenochtitlan, but that was tempered by this disdain for their beliefs and human sacrifice.
On 14 November 1519, Cortes seized the emperor Moctezuma II and ordered the destruction of all the religious relics of the Aztecs. He ordered a Catholic cross placed on the Templo Mayor. While Cortes left for Veracruz to confront Spaniards looking to arrest him, Pedro de Alvarado learned of a plan to attack the Spaniards, and staged a pre-emptive attack on the Aztecs in the Sacred Precinct while they celebrated a religious festival. Unarmed and trapped within the walls of the Sacred Precinct, an estimated 8,000–10,000 Aztec nobles were killed. When word of the massacre spread throughout the city, the people turned on the Spaniards, killing seven, wounding many, and driving the rest back to their quarters. The Spaniards were trapped between two Aztec forces and 68 were captured alive. Ten of these Spanish captives were immediately sacrificed at the Temple and their severed heads were thrown back to the Spaniards. The others were sacrificed at the Great Temple that night, which could be seen from the Spanish camps. The sacrificed Spaniards were flayed and their faces — with beards attached — were tanned and sent to allied towns, both to solicit assistance and to warn against betraying the alliance.
After the fall of Tenochtitlan in 1521, the lands controlled by the Aztecs became part of the Spanish empire. All the temples, including the Templo Mayor, were sacked, taking all objects of gold and other precious materials. Cortés, who had ordered the destruction of the existing capital, had a Mediterranean-style city built on the site. Essential elements of the old imperial center, including the Templo Mayor, were buried under similarly key features of the new Spanish city in what is now the historical downtown of the Mexico City. The Templo Mayor and Sacred Precinct were demolished and a Spanish church, later the main cathedral, was built on the western half of the precinct.
According to tradition, the Templo Mayor is located on the exact spot where the god Huitzilopochtli gave the Mexica people his sign that they had reached the promised land: an eagle on a nopal cactus with a snake in its mouth.
The Templo Mayor was partially a symbolic representation of the Hill of Coatepec, where according to Mexica myth, Huitzilopochtli was born. Huitzilopochtli emerged from his mother Coatlicue fully grown and fully armed to battle his sister Coyolxauhqui and her brothers the Centzon Huitznahua who intended to kill him and their mother. Huitzilopochtli was victorious, slaying and dismembering his sister. Her body was then thrown to the bottom of the hill. As the southern half of the Great Temple represented Coatepec (on the side dedicated to Huitzilopochtli), the great stone disk with Coyolxauhqui’s dismembered body was found at the foot of this side of the temple. The northern half represented Tonacatepetl, the mountain home of Tlaloc.
The sacred ballcourt and skull rack were located at the foot of the stairs of the twin temples, to mimic, like the stone disk, where Huitzilopochtli was said to have placed the goddess’ severed head. These locations served as a place for the reenactment of the mythical conflict.
The various levels of the Temple also represent the cosmology of the Aztec world. First of all, it is aligned with the cardinal directions with gates that connect to roads leading in these directions. This indicates the place where the plane of the world that humans live in intersects the thirteen levels of the heavens, called Topan and the nine levels of the underworld, called Mictlan.
Archaeologist Eduardo Matos Moctezuma, in his essay “Symbolism of the Templo Mayor,” posits that the orientation of the temple is indicative of the total vision that the Mexica had of the universe (cosmovision). He states that the “principal center, or navel, where the horizontal and vertical planes intersect, that is, the point from which the heavenly or upper plane and the plane of the Underworld begin and the four directions of the universe originate, is the Templo Mayor of Tenochtitlan.” Matos Moctezuma supports his supposition by claiming that the temple acts as an embodiment of a living myth where “all sacred power is concentrated and where all the levels intersect.” Said myth is the birth and struggle between Huitzilopochtli and Coyolxauhqui.
The Sacred Precinct of the Templo Mayor encompassed an area of almost 4,000 square meters (43,000 square feet) and it was surrounded by a wall called the “coatepantli” (serpent wall). Among the most important buildings were the ballcourt, the Calmecac (area for priests), and the temples dedicated to Quetzalcoatl, Tezcatlipoca and the sun. The Templo Mayor itself delineated the eastern side of the Sacred Precinct.
On the sides of the Templo Mayor, archeologists have excavated a number of palatial rooms and conjoining structures. One of the best preserved and most important is the Palace (or House) of the Eagle Warriors. This area dates back to the fourth stage of the temple, around 1469. It was excavated in 1981 and 1982 by José Francisco Hinojosa. It is a large L-shaped room with staircases decorated with sculptures of eagle heads. To enter this main room, one had to pass through an entrance guarded by two large sculpted representations of these warriors. The Eagle Warriors were a privileged class who were dedicated to the god Huitzilopochtli, and dressed to look like eagles. Adjoining this palace is the temple for these warriors—also known as the Red Temple. This temple shows clear Teotihuacan influence in its paintings (mostly in red) and the design of its altar. Almost all the interior walls of the House of the Eagles are decorated with beautiful paintings and contain long benches, which are also painted. These benches are composed of two panels. The upper one is a frieze with undulating serpents in bas-relief. The lower panel shows processions of armed warriors converging on a zacatapayolli, a grass ball into which the Mexica stuck bloody lancets during the ritual of autosacrifice. This palace specifically imitates much of the style of the Burnt Palace, located in the ruins of Tula. A number of important artifacts have been found in this area, the most important of which are two nearly identical large ceramic sculptures of Mictlantecuhtl, the god of death. Despite being found in fragile pieces, they were both reconstructed and are on display at the on-site museum.
Another conjoining area was dedicated to the Ocelot Warriors. Their temple, dedicated to the god Tezcatlipoca, lies under the current Museo de la Secretaría de Hacienda y Crédito Público to the south of the Templo Mayor.
The Calmecac was a residence hall for priests and a school for future priests, administrators and politicians, where they studied theology, literature, history and astronomy. Its exact location is on one side of what is now Donceles Street. The Temple of Quetzalcoatl was located to the west of the Templo Mayor. It is said that during the equinox, the sun rose between the shrines dedicated to Huitzilopochtli and Tlaloc and shone directly on this temple. Due to the god’s serpentine nature, the temple had a circular base instead of a rectangular one.
The ball field, called the tlachtli or teutlachtli, was similar to many sacred ball fields in Mesoamerica. Games were played barefoot, and players used their hips to move a heavy ball to stone rings. The field was located west of the Templo Mayor, near the twin staircases and oriented east-west. Next to this ball field was the “huey tzompanti” where the skulls of sacrifice victims were kept after being covered in stucco and decorated.
The Temple of the Sun was located west of the Templo Mayor also and its remains lie under the Metropolitan Cathedral. The project to shore up the cathedral at the end of the 20th century and beginning of the 21st brought to light a number of artifacts.
Most of the objects found in the Templo Mayor were offerings. Although many are of Mexica design, there are also abundant items from other peoples, brought in as tribute or through trade. Sculptures, flint knives, vessels, beads and other sumptuary ornaments—as well as minerals, plants and animals of all types, and the remains of human sacrifice—were among the items deposited in offerings. All of these fulfilled a specific function within the offering, depending on the symbolism of each object. In excavations at the Templo Mayor, different types of offerings have been found and have been grouped by researchers in terms of Time (the period in which the offering was deposited); Space (the location of the offering within the structure); Container (type and dimensions of the receptacle containing the objects); internal distribution (placement of objects within the offering) and value of the items. The offerings were usually contained in cavities, in stone urns, and in boxes made of slabs. These are found under floors; in platforms, architectural bodies, stairways and in temples. These offerings were placed accompanied by complex rituals following set temporal, spatial and symbolic patterns, depending on the intention of the offering.
The oldest Mexica objects, located in the second temple, are two urns which contain the remains of incinerated bones; one of the urns was made of obsidian and the other of alabaster. A small silver mask and a gold bell were found inside one urn, and second gold bell and two green stone beads were placed in the other.
Images of the gods Huehueteotl-Xiuhtecuhtli, together with Tlaloc, presided over most of the offerings found in the Templo Mayor. Representing fire and water respectively, this pair of deities probably symbolized the concept of “burning water,” a metaphor for warfare.
Another theme exhibited in this hall is autosacrifice, a ritual that was conducted in private as a personal act of communication with the gods. Widespread throughout the entire population, this practice was performed by perforating certain fleshy parts of the body—such as the earlobes, lips, tongue, chest, calves, et cetera—with obsidian blades, agave needles or bone perforators. Once the implement was covered with blood, it was inserted in straw balls called Zacatapayoli. The entirety was probably placed in ceremonial boxes—tepetlacalli—as an offering to the gods. Objects associated with human sacrifice are the “face blades” or knives decorated with eyes and teeth, as well as skull masks. Other ceremonial items include musical instruments, jewelry, and braziers for the burning of copal.
The museum of the Templo Mayor was built in 1987 to house the Templo Mayor Project and its finds—a project which continues work to this day. In 1991, the Urban Archeology Program was incorporated as part of the Templo Mayor Project whose mission is to excavate the oldest area of the city, around the main plaza. The museum building was built by architect Pedro Ramírez Vázquez, who envisioned a discreet structure that would blend in with the colonial surroundings. The museum has four floors, three of which are for permanent exhibitions and the fourth houses offices for the director, museum administration and research staff. Other departments are located in the basement, where there is also an auditorium.
The museum has eight main exhibition halls, called “salas”, each dedicated to a different theme. Room 1 is dedicated to the goddesses Coatlicue and Coyalxauhqui, mother and sister to Huitzlipochtli, respectively. Here are displayed the first finds associated with the temple, from the first tentative finds in the 19th century to the discovery of the huge stone disk of Coyolxauhqui, which initiated the Templo Mayor Project.
Room 2 is dedicated to the concepts of ritual and sacrifice in Tenochtitlan. This room contains urns where dignitaries where interred, funerary offerings, as well as objects associated with self and human sacrifice—such as musical instruments, knives and skulls.
Room 3 demonstrates the economics of the Aztec empire in the form of tribute and trade, with examples of finished products and raw materials from many parts of Mesoamerica. Sala 4 is dedicated to the god Huitzilopochtli. His shrine at the temple was the most important and largest. This room contains various images of him as well as offerings. Also located here are the two large ceramic statues of the god Mictlantecuhtli which were found in the House of the Eagle Warriors who were dedicated to Huitzilopochtli.
Room 5 is dedicated to Tlaloc, the other principal deity of the Aztecs and one of the oldest in Mesoamerica. This room contains various images of the god usually worked in green or volcanic stone or in ceramic. The most prized work is a large pot with the god’s face in high relief that still preserves much of the original blue paint. Room 6 is dedicated to the flora and fauna of Mesoamerica at this time, as most contained divine aspects for the Aztecs. Also many of the offerings found at the Templo Mayor were or were made from various plants and animals. Related to Room 6, Room 7 contains exhibits of the agricultural technology of the time, especially in the growing of corn and the construction of chinampas, the so-called “floating gardens”. The last room is Room 8, which is dedicated to the archeology and history of the site.
The archeological site lies just to the northeast of the Zocalo, or main plaza of Mexico City, just behind the Cathedral, in the block between Seminario and Justo Sierra streets (Zocalo metro station, Line 2).
