Teotihuacan

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.
