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.

On May 14th, ARX Project was back in Teotitlán del Valle to deliver the geophysical study report to the community museum and local authorities and plan the next stages of research.

“We are deeply grateful for this project and for the support it has received. For us Zapotec, this area that they are studying is very important. We are very interested in seeing more of our ancient roots.” - Roman Gutierrez Ruiz, president of the Teotitlan del Valle community museum.

We'll be sharing our preliminary findings over the coming days! To learn more and support further stages of this project, follow the link to our Patreon page

This Thursday, May 14th, ARX Project A.C. was in Teotitlán del Valle, Oaxaca, to deliver the Belguie-Xiguie geophysical study report. This document compiles the data obtained in 2025 and its interpretation by the team of experts from UNAM and INAH.

The report was delivered by Ludovic Celle, secretary of ARX Project, to Román Gutiérrez Ruiz, president of the community museum, in the presence of Mayor Benjamin Mendoza, Uriel Sánchez Sosa, director of COVATLAO, and the entire museum committee.
The report is presented in its full scientific format, and in a concise version for easier access. As an important complement to this physical delivery, a video conference was held, allowing the team of geophysicists and archaeologists to present the results and their interpretation directly. This meeting concluded with a Q&A session and a dialogue about planning the next stages of research, building upon this completed first phase.

The Belguie-Xiguie project team (ARX Project A.C., UNAM, and INAH) reiterates its gratitude to the authorities of Teotitlán del Valle for their warm welcome of this research project, which has allowed the opening of a new chapter in understanding this fascinating past, still waiting to be fully revealed.

Our team has just returned from an incredible expedition to Piedras Negras, one of the largest and most remote Maya cities along the course of the Usumacinta River.

To reach the site, our team—formed by Marco Vigato and our friends Juan Pablo Alonso, Trevor Grassi, and Frank Rogala, together with our amazing guides Ernesto, Alejandro, and Romario—had to brave treacherous rapids, dense jungle, and nights spent camping on an island in the Usumacinta River, dozens of miles from the nearest outpost of civilization, in the heart of one of the most pristine rainforests in all of Central America.

According to various indigenous and esoteric traditions, Piedras Negras may be the site of a legendary ancient library containing knowledge from a lost civilization.

Our exploration revealed numerous hints pointing to the existence of an extensive cave system beneath the site, which may help explain its ancient Maya name, Yo’k’ib — “The Great Entrance.”

We will soon be releasing a new video documenting this mysterious and remote ancient Maya site. Stay tuned!

A huge thank you to the incredible team at Explora Travel MX for making this adventure possible, and especially to our guides Ernesto and Alejandro. Be sure to check out their website and tours:

Special thanks as well to Fundación Defensores de la Naturaleza for providing logistical support for the expedition, and to Romario, our guide at Piedras Negras from Cooperativa La Técnica.

🌎📜 𝐓𝐡𝐞 𝐌𝐲𝐬𝐭𝐞𝐫𝐲 𝐨𝐟 𝐭𝐡𝐞 𝐋𝐚 𝐕𝐞𝐧𝐭𝐚 𝐒𝐭𝐨𝐧𝐞 𝐓𝐚𝐛𝐥𝐞𝐭𝐬 – 𝐀 𝐋𝐨𝐬𝐭 𝐎𝐥𝐦𝐞𝐜 𝐋𝐢𝐛𝐫𝐚𝐫𝐲? 🗿✨

Between 1943 and 1955, archaeologists at the ancient Olmec site of La Venta, Mexico, uncovered thousands of mysterious stone tablets buried deep beneath the ceremonial plaza. With only weeks before the start of oil exploration in the area, most of the tablets were quickly reburied — before any detailed examination could be made.

📖 In 1999, a nearly identical tablet was found at El Cascajal, just a few dozen miles from La Venta — this one covered in Olmec writing. Could the buried tablets of La Venta also have contained writing?

If so, an intact Olmec library of more than 20,000 stone tablets may still lie hidden beneath La Venta — a treasure trove of knowledge waiting to be rediscovered. What forgotten secrets of the earliest Mesoamerican civilization might they reveal?

⏳ How could such an astonishing discovery have been overlooked for over 80 years? History offers clues. The La Mojarra Stela, today recognized as the longest Epi-Olmec inscription, sat for an entire year in a museum basement before anyone noticed its 500+ glyphs — and eight more years passed before artificial light revealed additional columns of text.

With the limited technology of the 1940s and 1950s, subtle inscriptions on the La Venta tablets could easily have gone unnoticed — or perhaps even deliberately erased by the Olmecs themselves, as may also have been the case with the Cascajal Block.

Across the ancient world, from Mesopotamia to the Near East, similar libraries of clay and stone tablets have been found — often made of serpentine stone, prized for its durability and sacred symbolism.

❓ Why did the Olmecs conceal thousands of tablets beneath their most sacred site?
❓ And could an entire Olmec library still be waiting beneath the jungles of Tabasco?
