Explanation:Teotihuacán, (Nahuatl: “The City of the Gods”) the most important and largest city of pre-Aztec central Mexico, located about 30 miles (50 km) northeast of modern Mexico City. At its apogee (c. 500 ce), it encompassed some 8 square miles (20 square km) and supported a population estimated at 125,000–200,000, making it, at the time, one of the largest cities in the world. It was the region’s major economic as well as religious centre. Teotihuacán was designated a UNESCO World Heritage site in 1987.
