(3) Chichen Itza is a Mayan city which was established in the 8th century CE. It is situated in Yucatan, Mexico. Chichen Itza was one of the largest Maya cities and it was likely to have been one of the mythical great cities, or Tollans, referred to in later Mesoamerican literature. The city may have had the most diverse population in the Maya world, a factor that could have contributed to the variety of architectural styles at the site.
