Chichen Itza was a major focal point in the Northern Maya Lowlands from the Late Classic through the Terminal Classic and into the early portion of the Postclassic period. The site exhibits a multitude of architectural styles. 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.
Tulum is the site of a pre-Columbian Mayan walled city which served as a major port for Coba, in the Mexican state of Quintana Roo. The ruins are situated on 12-meter-tall cliffs along the east coast of the Yucatán Peninsula on the Caribbean Sea. Tulum was one of the last cities built and inhabited by the Maya. By the end of the 16th century, the site was abandoned. One of the best-preserved coastal Maya sites, Tulum is today a popular site for tourists.
