El Tajín
El Tajín is a pre-Columbian archeological site in southern Mexico and is one of the largest and most important cities of the Classic era of Mesoamerica. A part of the Classic Veracruz culture, El Tajín flourished from 600 to 1200 CE and during this time numerous temples, palaces, ballcourts, and pyramids were built. From the time the city fell, in 1230, to 1785, no European seems to have known of its existence, until a government inspector chanced upon the Pyramid of the Niches.
