MEXICO CITY.- In the dense landscape of southern Quintana Roo, a forgotten Maya city is beginning to come back into view. What started as a report from local residents has led archaeologists to document a remarkable pre-Hispanic settlement—one that is now officially recognized by the Instituto Nacional de Antropología e Historia (INAH).

The site, known as El Jefeciño, owes its name to the sheer scale of its architecture. Spread across what is believed to be at least 100 hectares, the settlement includes around 80 structures, some rising more than 14 meters high. Though still largely unexplored, its presence adds a new chapter to the story of the ancient Maya in this part of Mexico.

A discovery sparked by the community

The rediscovery of El Jefeciño is a reminder of how local knowledge continues to play a vital role in preserving cultural heritage. Residents in the municipality of Othón P. Blanco first alerted authorities during ongoing fieldwork tied to the Maya Train Archaeological Salvage Project.

Archaeologist Manuel Pérez Rivas, who leads efforts along this section of the project, oversaw the initial identification. From there, a team of specialists moved in to document what they were beginning to suspect was far more than a minor site.

Mexico’s Secretary of Culture, Claudia Curiel de Icaza, underscored the broader significance of the find, noting that it not only strengthens the protection of archaeological heritage but also highlights the crucial role communities play in safeguarding shared history.

Architecture that speaks of a powerful past

At first glance, what stands out most about El Jefeciño is its architecture. The structures reflect the Petén style—a hallmark of the Maya Classic period (250–900 CE)—recognized for its imposing vaulted buildings, rounded corners, and distinctive apron moldings.

According to archaeologist Sonny Moisés Ojeda González, who co-led the site’s documentation alongside Diana Karina Blancas Olvera, the central area appears to be organized around a plaza shaped like a “C.” Five major buildings dominate this core, suggesting a space that may once have served ceremonial or administrative functions.

Even in its current state—partially covered by vegetation and time—the site conveys a sense of order and intention, hinting at a once-thriving urban center.

Traces of life, ritual, and construction

Beyond its scale, El Jefeciño is already offering glimpses into the lives of its ancient inhabitants.

In one structure, researchers identified remnants of stucco adorned with decorative mural painting. Though still under study, the pigments—white, orange, and bands of red—suggest a visual language that may have held symbolic meaning.

Nearby, fragments of a human skeleton were found, possibly part of a burial context. For now, these elements remain untouched, as the site has not undergone full excavation and all materials are being preserved in situ.

Other discoveries point to the complexity of the city’s development. Archaeologists have identified at least three construction phases, with evidence that suggests there could be more. Beneath visible layers lie earlier structures, including a substructure with characteristic apron molding and the remains of staircases that once connected different levels of the buildings.

Inside some of these constructions, three well-preserved Maya vaults—built using corbelled techniques—have also been documented, offering rare insight into ancient engineering practices.

A site with much more to reveal

Despite these early findings, El Jefeciño is still in its infancy as an archaeological study. Much of the site remains hidden, and its true scale may extend beyond current estimates.

Future research is expected to include LiDAR mapping, a technology that can reveal hidden structures beneath dense vegetation. This will help archaeologists better understand how the city was organized and how it may have connected to other Maya settlements in the region.

Expanding the map of the ancient Maya

For researchers, the importance of El Jefeciño goes beyond its architecture. Each new site helps piece together the broader network of Maya cities that once flourished across the Yucatán Peninsula.

As studies continue, this newly registered settlement could shed light on regional dynamics—how communities interacted, traded, and evolved over centuries.

For now, El Jefeciño stands as a powerful reminder that even in well-studied regions, the past still has secrets waiting to be uncovered.
