Overview

About this site

What the sources say

Teotihuacan (; Spanish: Teotihuacán, Spanish pronunciation: [teotiwaˈkan] ; Classical Nahuatl: Teōtīhuacān, Classical Nahuatl pronunciation: [te.oːtiːˈwakaːn] ) is an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, which is located in the State of Mexico, 40 kilometers (25 mi) northeast of modern-day Mexico City.

Teotihuacan is known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas, namely the Pyramid of the Sun and the Pyramid of the Moon. Although close to Mexico City, Teotihuacan was not a Mexica (i.e. Aztec) city, and it predates the Aztec Empire by many centuries. At its zenith, perhaps in the first half of the first millennium (1 CE to 500 CE), Teotihuacan was the largest city in the Americas. Its population has been estimated to be at least 25,000, but likely sat around 100,000 during its height, potentially making it the sixth-largest city in the world during its epoch.

The city covered twenty-one square kilometres (8 sq mi) and 80 to 90 percent of the total population of the valley resided in Teotihuacan. Apart from the pyramids, Teotihuacan is also anthropologically significant for its complex, multi-family residential compounds, the Avenue of the Dead, and its vibrant, well-preserved murals. Additionally, Teotihuacan exported fine obsidian tools found throughout Mesoamerica. The city is thought to have been established around 100 BCE, with major monuments continuously under construction until about 250 CE. The city may have lasted until sometime between the 7th and 8th centuries CE, but its major monuments were sacked and systematically burned around 550 CE. Its collapse might be related to the extreme weather events of 535–536.

Teotihuacan began as a religious center in the Mexican Plateau around the first century CE. It became the largest and most populated center in the pre-Columbian Americas. Teotihuacan was home to multi-floor apartment compounds built to accommodate the large population. The term Teotihuacan (or Teotihuacano) is also used to refer to the whole civilization and cultural complex associated with the site. Although it is a subject of debate whether Teotihuacan was the center of a state empire, its influence throughout Mesoamerica is well documented. Evidence of Teotihuacano presence is found at numerous sites in Veracruz and the Maya region. The later Aztecs saw these magnificent ruins and claimed a common ancestry with the Teotihuacanos, modifying and adopting aspects of their culture.

The ethnicity of the inhabitants of Teotihuacan is the subject of debate. Possible candidates are the Nahuas, Otomi, or Totonac. Other scholars have suggested that Teotihuacan was multi-ethnic, due to the discovery of cultural aspects connected to the Maya as well as Oto-Pamean people. It is clear that many different cultural groups lived in Teotihuacan during the height of its power, with migrants coming from all over, but especially from Oaxaca and the Gulf Coast. After the collapse of Teotihuacan, central Mexico was dominated by more regional powers, notably Xochicalco and Tula.

The city and the archeological site are located in what is now the San Juan Teotihuacán municipality in the State of México, approximately 40 kilometers (25 mi) northeast of Mexico City. The site covers a total surface area of 83 square kilometers (32 sq mi) and was designated a UNESCO World Heritage Site in 1987. It was the second most-visited archeological site in Mexico in 2024, receiving 1,313,321 visitors.

Teotihuacan is an ancient Mesoamerican city in a sub-valley of the Valley of Mexico, in the State of Mexico, 40 kilometers (25 mi) northeast of modern-day Mexico City. It is known for some of the most architecturally significant pyramids of the pre-Columbian Americas, the Pyramid of the Sun and the Pyramid of the Moon. Although close to Mexico City, it was not an Aztec city and predates the Aztec Empire by many centuries.

At its zenith, perhaps in the first half of the first millennium (1 CE to 500 CE), Teotihuacan was the largest city in the Americas. Its population has been estimated at least 25,000 but likely around 100,000 at its height. The city covered twenty-one square kilometres (8 sq mi), and 80 to 90 percent of the population of the valley lived there. The site as a whole covers 83 square kilometers (32 sq mi) and was designated a UNESCO World Heritage Site in 1987.

Apart from the pyramids, the city is significant for its multi-family residential compounds, including multi-floor apartment compounds, the Avenue of the Dead, and well-preserved murals. It also exported fine obsidian tools found throughout Mesoamerica. Its influence is well documented, with evidence of Teotihuacano presence at numerous sites in Veracruz and the Maya region, though it is debated whether it was the center of a state empire.

The city is thought to have been established around 100 BCE, with major monuments under construction until about 250 CE.

The ethnicity of its inhabitants is debated, with the Nahuas, Otomi or Totonac as possible candidates, and other scholars suggest it was multi-ethnic, with migrants from all over, especially Oaxaca and the Gulf Coast. The original name is unknown, though Maya hieroglyphic texts give it as puh, "Place of Reeds". The name Teotihuacan was given by the Nahuatl-speaking Aztecs centuries after the fall, and has been glossed as "birthplace of the gods", reflecting Nahua creation myths. The Aztecs saw the ruins and claimed a common ancestry with the Teotihuacanos.

Etymology

Sources for this section

The name Teōtīhuacān was given by the Nahuatl-speaking Aztecs centuries after the fall of the city around 550 CE. The term has been glossed as "birthplace of the gods", or "place where gods were born", reflecting Nahua creation myths that were said to occur in Teotihuacan. Nahuatl scholar Thelma D. Sullivan interprets the name as "place of those who have the road of the gods." This is because the Aztecs believed that the gods created the universe at that site. The name is pronounced [te.oːtiːˈwakaːn] in Nahuatl, with the stress on the syllable wa. By normal Nahuatl orthographic conventions, a written accent mark would not appear in that position. Both this pronunciation and the Spanish pronunciation [te.otiwaˈkan] are used; in Spanish the stress falls on the second to last vowel, as long as the last letter in the word is a vowel, an n, or an s, so again an accent mark is not used.

The original name of the city is unknown, but it appears in hieroglyphic texts from the Maya region as puh, or "Place of Reeds". This suggests that, in the Maya civilization of the Classic period, Teotihuacan was understood as a Place of Reeds similar to other Postclassic Central Mexican settlements that took the name of Tollan, such as Tula-Hidalgo and Cholula.

This naming convention led to much confusion in the early 20th century, as scholars debated whether Teotihuacan or Tula-Hidalgo was the Tollan described by 16th-century chronicles. It now seems clear that Tollan may be understood as a generic Nahua term applied to any large settlement. In the Mesoamerican concept of urbanism, Tollan and other language equivalents serve as a metaphor, linking the bundles of reeds and rushes that formed part of the lacustrine environment of the Valley of Mexico and the large gathering of people in a city.

As of January 23, 2018, the name Teotihuacan has come under scrutiny by experts, who now feel that the site's name may have been changed by Spanish colonizers in the 16th century. Archeologist Verónica Ortega of the National Institute of Anthropology and History states that the city appears to have actually been named Teohuacan, meaning "City of the Sun" rather than "City of the Gods", as the current name suggests.
