Teotihuacan

Teotihuacan is an ancient Mesoamerican city located in the Basin of Mexico, about 40 kilometers northeast of present-day Mexico City, within the Mexican state of Mexico. The city developed between roughly 100 BCE and 250 CE and reached its height between the 4th and 6th centuries CE, when it may have housed tens or hundreds of thousands of inhabitants. The name Teotihuacan comes from Nahuatl and is commonly translated as “the place where the gods were born” or “birthplace of the gods”; the people who built the city did not use that name for themselves, and much about their language remains undeciphered.

The urban layout is renowned for its planned grid, wide avenues, and monumental architecture. The central thoroughfare, the Avenue of the Dead, connects a ceremonial heart with the city’s major pyramids and palaces. The Pyramid of the Sun and the Pyramid of the Moon stand as two of the city’s most prominent structures, flanking the ceremonial Plaza of the Moon. The Ciudadela complex houses the Temple of the Feathered Serpent (Quetzalcoatl). The city exhibits distinctive talud-tablero architecture and sophisticated water management, including reservoirs and canals, reflecting advanced urban planning.

Teotihuacan was a multiethnic metropolis with a centralized political and religious system, yet its rulers remain unidentified in the archaeological record. The city influenced surrounding regions and later Mesoamerican cultures, including the Toltecs and, indirectly, the Mexica (Aztec). Writing in Teotihuacan is limited and not yet fully deciphered, leaving many core aspects of governance and daily life unresolved.

The site declined and was largely abandoned after the 6th century CE, for reasons debated among scholars. It was rediscovered in the postcolonial period and is now a UNESCO World Heritage Site and a major archaeological and tourist destination.
