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.El Tajín, named after the Totonac rain god, was named a World Heritage site in 1992, due to its cultural importance and its architecture. This architecture includes the use of decorative niches and cement in forms unknown in the rest of Mesoamerica. Its best-known monument is the Pyramid of the Niches, but other important monuments include the Arroyo Group, the North and South Ballcourts and the palaces of Tajín Chico. In total there have been 20 ballcourts discovered at this site, (the last 3 being discovered in March 2013). Since the 1970s, El Tajin has been the most important archeological site in Veracruz for tourists, attracting 386,406 visitors in 2017.It is also the site of the annual Cumbre Tajin Festival, which occurs each March featuring indigenous and foreign cultural events as well as concerts by popular musicians.
