Chichen Itza Spanish: Chichén Itzá at the mouth of the well of the Itza, was a large pre-Columbian city built by the Maya civilization.
The archaeological site is located in the municipality of Tinum, in the Mexican state of Yucatán.
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.
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 land under the monuments had been privately-owned until 29 March 2010, when it was purchased by the state of Yucatán.
