Core Location Summary
Teotihuacan is an ancient Mesoamerican city situated in the Basin of Mexico, roughly 40 kilometers (25 miles) northeast of modern Mexico City. The site lies within the municipality of San Juan Teotihuacan in the State of Mexico, close to the towns of San Juan Teotihuacan and San Martín de las Pirámides. It is positioned at approximately 19.692° N, 98.843° W, near the northeastern shore of the former Lake Texcoco. Today the archaeological zone is easily reached via the MEX 115 and MEX 132 federal highways, with the nearest sizable town being San Juan Teotihuacan, about 8 kilometers from the central complexes.
Geographic Region: The Basin of Mexico
The Basin of Mexico is a high-altitude valley at approximately 2,240 meters (7,350 feet) above sea level, surrounded by mountains and volcanoes. Teotihuacan occupies a relatively flat stretch within this basin, near the southern shore of what was once Lake Texcoco. Its placement in this fertile valley supported intensive agriculture and dense settlement. The site’s orientation aligns with Cerro Gordo to the north and key solar events, while the surrounding landscape historically included lakes, wetlands, and causeways that connected major centers. Contemporary settlements encroach on the periphery, but the core ceremonial and urban zone remains distinct within the regional lowlands.

Site Coordinates and Topography
Teotihuacan sits at roughly 19.692° N, 98.843° W, on a plateau that gently slopes toward the central avenues and plazas. The terrain is mostly flat to undulating, with subtle elevation changes that guided urban planning and ceremonial axis alignment. Soils in the valley are lacustrine and alluvial, supporting maize, maguey, and other crops in pre-Columbian times. The site’s position relative to springs, seasonal streams, and causeways played a role in water management and ceremonial processions. Small volcanic outcrops and limestone quarries lie nearby, providing construction materials for platforms, walls, and sculpture.
Historical Settlement and Urban Layout
Occupation at Teotihuacan spans several phases, with major pyramid-compound constructions occurring between approximately 100 BCE and 250 CE. The city’s plan centers on the Avenue of the Dead, a broad ceremonial thoroughfare that connects the Temple of the Feathered Serpent (in the south) with the Pyramid of the Moon (to the north). Key neighborhoods and compound groups—such as the Palace of Quetzalpalcatl, the Citadel, and the Ciudadela—organize the site into functional and ritual districts. Causeways and linear avenues extend outward, linking civic-ceremonial cores with agricultural fields, settlements, and regional exchange nodes.

Transport, Access, and Visitor Context
Visitors commonly reach Teotihuacan by car, bus, or organized tour from Mexico City, with travel time typically between 60 and 90 minutes depending on traffic. Public transportation options include buses from northern Mexico City terminals that drop passengers at the San Juan Teotihuacan entrance, from which a short ride or walk leads to the archaeological zone. On-site signage, site museums, and guided tours reference the layout of plazas, pyramids, and residential quarters. The site’s regional connectivity, both ancient and modern, underscores its role as a hub within the Basin of Mexico’s network of settlements and trade routes.
Preservation and Regional Development
Teotihuacan is protected as a national archaeological zone and is recognized as a UNESCO World Heritage site. Urban growth in the municipalities of Teotihuacan, Acolman, and surrounding areas continues to shape land use and infrastructure planning. Conservation efforts focus on stabilizing monuments, managing visitor impact, and maintaining the integrity of ceremonial axes and causeways. Zoning regulations and regional planning initiatives aim to balance tourism, local livelihoods, and the protection of archaeological landscapes, ensuring that the site remains a durable focus for research and public engagement.
