Teotihuacan /teɪˌoʊtiːwəˈkɑːn/, also written Teotihuacán (Spanish  teotiwa'kan (help·info)), was a pre-Columbian Mesoamerican city located in a sub valley of the Valley of Mexico, located in the State of Mexico 30 miles (48 km) northeast of modern-day Mexico City, known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas. Apart from the pyramids, Teotihuacan is also anthropologically significant for its complex, multi-family residential compounds; the Avenue of the Dead; and the small portion of its vibrant murals that have been exceptionally well-preserved. Additionally, Teotihuacan exported fine obsidian tools that garnered high prestige and widespread utilization throughout Mesoamerica.
