Naachtun

Naachtun is an archaeological site of the pre-Columbian Maya civilization, situated at the northeastern perimeter of the Mirador Basin region in the southern Maya lowlands, now in the modern-day Department of El Petén, northern Guatemala. Naachtun was a major center of the region by the late Formative (or Pre-Classic) Period, and was one of the few Formative Period Mirador Basin centers which continued to flourish into the succeeding Classic period.
