Plan de Ayutla, Maya archaeological site in Ocosingo, Mexico.

Plan de Ayutla is a Maya archaeological site in Ocosingo containing roughly 72 buildings arranged across three natural hills that served as ceremonial centers. The structures surround three main plazas that formed the heart of this ancient settlement, with the tallest buildings positioned on elevated terrain.

The settlement was founded around 150 BCE and developed into an urban center by 50 BCE. This makes it one of the earliest cities in the Upper Usumacinta region and demonstrates how Maya civilization established itself in this area during the early period.

The modern name comes from the nearby Tzeltal community of Plan de Ayutla. The site may be ancient Ak'e, "Turtle," or Sak Tz'i', "White Dog," a kingdom whose rulers included Aj Sak Maax and Yete' K'inich. Colonial reports mention a lord called Zactzi among Lacandon leaders.

The site can be reached by traveling to Nueva Palestina and then following a gravel road into the jungle. Visitors should wear sturdy shoes and be prepared for uneven terrain and thick vegetation.

Plan de Ayutla has an ancient theater built for elite audiences, a feature not found at other Maya sites in the region. Its North Acropolis closely mirrors the Grand Acropolis of Piedras Negras, hinting at a political link between the two cities. The site also shares architectural traits with Tonina, such as its ballcourt layout and column-shaped altars.
