You can now read the full findings of our project in Teotitlán del Valle!

Around 30 km southeast of Oaxaca de Juárez lies Teotitlán del Valle (Xiguie). In the Tlacolula Valley Archaeological Corridor, the small town holds on to traditions influenced by Zapotec, Mixtec, and Aztec history. It’s known for its textile art, traditional dance, and the Belguie archaeological site. The site houses centuries of zapotec heritage, but has, in great part, remained a mystery until now.

Deep in the jungles of Guatemala, the ancient Maya city of Piedras Negras has long been linked to an extraordinary legend: that somewhere beneath its ruins may lie a hidden Hall of Records, a vast subterranean library said to preserve the knowledge of a lost civilization far older than the Maya themselves.

Myth, esoteric tradition… or a clue to something still waiting to be discovered?

Earlier this year, we traveled down the Usumacinta River and deep into the jungle to investigate the mystery ourselves.

The final feature from the non-invasive geophysical survey of Teotitlán de Valle is the colonial engineering effort. In the 16th and 17th centuries, large volumes of fill from the demolition of the prehispanic structures were used to level the terrain to build the church and atrium.

We'll be delving deeper into these divings in the coming weeks, but one thing is clear: the archaeological zone is more extensive than what is visible today.

The second feature found at Teotitlán de Valle is Funerary chambers: At least one major geophysical anomaly compatible with the existence of at least one monumental Zapotec tomb underneath the patio.

“These findings are not merely scientific data: they are an opportunity for the community, authorities, and specialists to work together to preserve a history that continues to live beneath our feet.”

In Teotitlán de Valle, with non-destructive technologies, we found three key archaeological features.

The first is a group of ceremonial and palatial structures arranged around an open patio like the palaces of Mitla, centered around the present-day Church of Our Lady of Nativity.
