Visit to the archaeological site of Teotihuacan, an Aztec site where the heights of the Pyramids of the Sun and Moon give a sense of the scale of this city, the largest in the pre-Columbian world. With pyramids among the largest ever built, a majestic Avenue of the Dead lined with a multitude of palaces and temples, and countless residential, artisan, and merchant quarters, Teotihuacan stands as the first true city of Mesoamerica. Its prestige was such that it gave rise to many myths: it was in this city, itself said to have been built by the gods, that the sun, the moon, and our universe were created. Teotihuacan is listed as a UNESCO World Heritage Site.
