Chichen Itza was a large pre-Columbian city built by the Maya people of the Post Classic. The archaeological site is located in the municipality of Tinum, in the Mexican state of Yucatán.
Chichen Itza was a major focal point in the northern Maya lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c.AD 800–900) and into the early portion of the Early Postclassic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.
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.
The ruins of Chichen Itza are federal property, and the site’s stewardship is maintained by Mexico’s Instituto Nacional de Antropología e Historia (National Institute of Anthropology and History). The land under the monuments had been privately owned until 29 March 2010, when it was purchased by the state of Yucatán.
Chichen Itza is one of the most visited archaeological sites in Mexico; an estimated 1.2 million tourists visit the ruins every year.
