Located in the state of Veracruz Mexido, El Tajin was at its height from the early 9th to the early 13th century. It became the most important center in north-east Mesoamerica . Its cultural influence extended all along the Gulf and penetrated into the Maya region. El Tajín flourished from 600 to 1200 C.E. 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.
