Nakbe

Nakbe is one of the largest early Maya archaeological sites. Nakbe is located in the Mirador Basin, in the Petén region of Guatemala, approximately 13 kilometers south of the largest Maya city of El Mirador. Excavations at Nakbe suggest that habitation began at the site during the Early Formative period and continued to be a large site until its collapse during the Terminal Formative period. The fall of Nakbe and El Mirador took place at roughly the same time.
