Located in the Caribbean Sea about 130 kilometers away from Cancun, it is a relatively prosperous religious urban relic at the end of the Mayan culture in the 14th century. It is surrounded by stone walls up to 3.3 meters high. The buildings in the ancient city are all made of stone and carved with patterns. It is said that this is a relatively well-preserved ancient city of the Mayan and Toltec people in Mexico so far.
