Discover the ancient history of Mexico’s largest active archeological site
Located more than a kilometer from the main structures of Chichen Itza, Chichen Viejo (Old Chichen) is an archaeological zone that includes several ancient Mayan structures known as the Initial Series Group. Chichen Viejo is thought to be an extensive compound once home to Mayan elites. The compound is larger than many of the villas of Greek and Roman kings. Archaeologists have dated a stone lintel at the site back to 619 A.D; the oldest hieroglyphics discovered at Chichen Itza. The ruins of the site are primarily of Puuc-style architecture.

This area is not currently open to the public and is the site of active archaeological excavation and restoration work by the National Institute of Anthropology and History (NIAH).
