Teotihuacan also written Teotihuacan, with a Spanish orthographic accent on the last syllable is an enormous archaeological site in the Basin of Mexico, just 30 miles northeast of Mexico City, containing some of the largest pyramidal structures built in the pre-Columbian Americas.
Apart from the pyramidal structures, Teotihuacan is also known for its large residential complexes, the Avenue of the Dead, and numerous colorful, well-preserved murals. Additionally, Teotihuacan produced a thin orange pottery style that spread through Mesoamerica.
The city and the archaeological site are located in what is now the San Juan Teotihuacán municipality in the State of MéXico, Mexico, approximately 40 kilometres (25 mi) northeast of Mexico City. The site covers a total surface area of 83 square kilometres (32 sq mi) and was designated a UNESCO World Heritage Site in 1987. It is the most visited archaeological site in Mexico.
During Aztec times, the city was a place of pilgrimage and identified with the myth of Tollan, the place where the sun was created. Teotihuacan astonished the Spanish conquistadores during the post-conquest era.Today Teotihuacan is one of the most noted archaeological attractions in Mexico.
The city's broad central avenue, called "Avenue of the Dead" (a translation from its Nahuatl name Miccoatli), is flanked by impressive ceremonial architecture, including the immense Pyramid of the Sun (Third largest in the New World after the Great Pyramid of Cholula
) and the Pyramid of the Moon. Along the Avenue of the Dead are many smaller talud-tablero platforms.
The Aztecs believed they were tombs, inspiring the name of the avenue. Now scholars have established these were ceremonial platforms that were topped with temples.
