MEXICO CITY.- Mexico has revealed what experts are already calling the most important archaeological discovery of the past decade: a Zapotec tomb dating back more than 1,400 years, to around 600 CE.

The announcement was made on Friday morning during the daily presidential briefing by Claudia Sheinbaum Pardo, who highlighted the exceptional state of preservation and the wealth of information the tomb offers about one of Mesoamerica’s great civilizations.

“This is the most significant archaeological discovery of the last ten years in Mexico,” the president said, stressing that the find provides rare and direct insight into the social structure, beliefs, and ritual life of the Zapotec people. “It is powerful evidence of Mexico’s millennia-old cultural greatness.”

An extraordinary tomb in the heart of Oaxaca

The tomb was discovered in the Central Valleys of Oaxaca, a region long recognized as the cradle of Zapotec civilization. What sets this find apart is not only its age, but the extraordinary survival of its architectural features, sculptures, and mural paintings.

According to specialists from the Instituto Nacional de Antropología e Historia (INAH), the tomb provides invaluable information about Zapotec funerary rituals, social hierarchy, and worldview—elements that are rarely preserved together at this level of detail.

On social media, Mexico’s Secretary of Culture described the discovery as “exceptional,” noting that the tomb’s architecture and mural paintings vividly reflect Zapotec ideas about life, death, power, and the sacred. “It is a clear reminder,” she wrote, “of a civilization whose legacy continues to be studied, protected, and shared with society today.”

Symbols of power, death, and ancestry

Among the most striking features is the entrance to the tomb itself. An owl—an animal associated with night and death in Zapotec cosmology—presides over the antechamber. Its beak partially covers the painted and stuccoed face of a Zapotec lord, believed to represent the ancestor for whom the tomb was built. Archaeologists suggest that descendants may have viewed this figure as an intermediary between the living and the divine.

The threshold is framed by a stone lintel topped with a frieze of engraved slabs bearing calendrical names. Carved into the door jambs are the figures of a man and a woman, both wearing elaborate headdresses and holding ritual objects—possibly guardians of the sacred space.

Inside the funerary chamber, sections of an extraordinary mural remain in place. Painted in shades of ochre, white, green, red, and blue, the scene depicts a procession of figures carrying bags of copal resin, walking solemnly toward the entrance of the tomb.

Preservation and research underway

An interdisciplinary team from INAH Oaxaca is currently working to conserve and study the site. One of the most urgent challenges is stabilizing the mural paintings, which are threatened by roots, insects, and sudden changes in temperature and humidity.

At the same time, researchers are conducting ceramic, iconographic, and epigraphic analyses, as well as physical anthropology studies of the human remains. Together, these investigations aim to deepen understanding of the rituals, symbols, and burial practices associated with this elite Zapotec tomb.

A discovery of national importance

Because of its architectural quality and decorative richness, archaeologists are already comparing the tomb to other major Zapotec funerary complexes in the region. The consensus is clear: this discovery significantly reshapes what we know about Zapotec society and its artistic and symbolic sophistication.

More than a remarkable find, the tomb stands as a rare and vivid connection to Mexico’s deep past—one that continues to speak, centuries later, through stone, pigment, and ritual memory.
