Naachtun, Maya archaeological site in Petén Department, Guatemala

Naachtun is an ancient Maya site located deep in the jungle of the Petén Department, near the border between Mexico and Guatemala. It is made up of three main groups of structures, including pyramid temples, an acropolis, two ballcourts and residential buildings, all linked by raised stone causeways.

Naachtun was first documented in 1922 by the archaeologist Sylvanus Morley, and it served as a key point between Tikal and Calakmul during the Classic period. Settlement began as early as the Late Formative and continued well after many nearby centers in the Mirador Basin had been abandoned.

The name Naachtun comes from a Maya term meaning "distant stones", given by Sylvanus Morley because of the site's remoteness; its ancient name was Masuul. Stela 18, found on the terrace in front of Structure XXXVIII in Group B, shows a gigantic woman crushing a bound captive beneath her. A carved stela depicting the "Lady of Tikal" was recently discovered here.

The site is far from main roads and can only be reached with a 4x4 vehicle and solid planning ahead of time. Traveling with experienced local guides is strongly advised, and visitors should bring gear suited to a dense, humid jungle.

Around 45 inscribed stone slabs were found here, which is an unusually large number for a center of this size. This concentration of carved monuments makes Naachtun one of the most important sources for studying how Classic Maya cities were politically connected.
