Ancient Maya Structure Discovered During Maya Train Construction in Yucatan

Merida, Yucatan — Archaeologists have uncovered a Maya structure more than 1,100 years old during salvage work for the Maya Train project in Yucatan, Mexico’s National Institute of Anthropology and History (INAH) announced.

The quadrangular structure, measuring about six meters per side, features three superimposed levels with a possible upper room, distinctive construction elements such as benches and walls, and a cavity carved into bedrock. It dates to the Classic period (400–750 A.D.) and is believed to have been part of a residential unit.

Researchers noted that the architecture is unusual for traditional dwellings, sparking interest in its possible ceremonial or religious functions. Key finds include a limestone “panucho” associated with traditional beehives, an arrangement of flat stones suggesting a symbolic space, and an offering containing a vessel with shell and green stone beads.

The site is located in an archaeological corridor west of Merida, a key area for understanding settlements in the northern Yucatan Peninsula. INAH researchers have linked the discovery to other important Maya sites such as Chunchucmil, a pre-Hispanic commercial center, and Oxkintok, a regional ruling site, suggesting the area was part of a broader trade and cultural network connecting the coast with inland communities.

To preserve the structure, INAH has implemented measures including covering it with geotextile, protecting the ground in work areas, and creating a detailed record using photogrammetry. These actions aim to ensure the site’s conservation without halting infrastructure development.

The discovery adds to the understanding of Maya civilization and reinforces the cultural and historical identity of Mexico’s southeastern region, which remains rich in pre-Hispanic vestiges.
