Maybe not as well known as Teotihuacan, Chichen Itza or even the neighbor Palenquebut Toniná It is one of the great archaeological treasures of Mexico. The necropolis experienced its heyday between 600 and 900 AD and today it is preserved as one of the most fascinating complexes of the Mayan area and pre-Hispanic urbanism. In fact, it is crowned by a unique pyramidal structure in the region that is taller than the famous pyramid of the sun of Teotihuacan.
Therefore, to guarantee its conservation, the Mexican Government has just made a radical decision: expropriate 9.2 hectares of the environment so that they become directly dependent on the National Institute of Anthropology (INAH).
What has happened? That Mexico has just shown that it is willing to pull expropriation decree to protect your assets. And he has also done it in a practical way. The Executive led by Claudia Sheinbaum has announced that the National Institute of Anthropology and History has “taken possession” of a 9.22-h property in the vicinity of the Toniná site, in the state of Chiapas.
The curious thing is how that land has been obtained, until recently in private hands. The transfer has been possible thanks to a decree that gave the green light to the sale in favor of the INAH. “The action arises from a cause of public utility, promoted in December 2025 by Culture,” clarify the authorities.


Why have they done it? The Executive’s objective is twofold: to facilitate the conservation and research of the environment. In the words of INAH itself, the idea is to “guarantee the optimal conditions” of the site. “Toniná is an essential part of the living history of Chiapas and Mexico. This decree protects an asset of the nation and contributes to the exercise of cultural rights through access to knowledge and historical memory,” reasons Claudia Curiel de Icaza, Secretary of Culture.
The leader insists that with the measure the State reinforces its capacity to “preserve heritage, ensure its management with technical criteria and sustain conservation, restoration and research tasks.” From now on, the INAH will expand its capacity to monitor, care for and study the ancient Mayan city.
Why is it important? For several reasons. Beyond the legal formula used or its advantages to protect, conserve and study the site, the measure is interesting because Mexico wants to take advantage of it to promote Toniná.
“In the archaeological zone, a comprehensive reactivation program will be implemented that will create a structured route for its eventual reopening,” keep it up the INAH. In fact, one of the objectives is to promote “responsible tourism.”
Is Toniná so important? Yes. And that is another reason why the recovery of the nine hectares has generated so much expectation. Located on the border between the Mayan highlands and the lowlands, the inhabitants of ancient Toniná left a fascinating acropolis, with overlapping platforms and a pyramidal structure that archaeologists considered “unique” in the Mayan world. In fact, it surpasses in height the famous Pyramid of the Sun of Teotihuacán, 65 meters.
“The richness of this archaeological zone makes it comparable to other large sites in Chiapas, such as Palenque. Its heyday goes from the year 600 to 900, within the Classic period, and it was the last witness to the decline of the so-called Old Mayan Empire,” explains the INAH. The most famous governor in its history was Tzots Choj (‘Tiger-Bat’) and its greatest archaeological treasure is offered by its acropolis and central plaza.
In it we find a staircase of 260 steps, the enormous pyramidal structure and a labyrinth of temples, palaces and roads. Experts have also located an altar for sacrifices and spaces to play ball.
How long have we known her? The first to tell us about Toniná was Brother Jacinto Garridoin the 17th century, but the site has continued to fascinate experts since then. During the 19th century, expeditions continued and throughout the 20th century (especially between the 1970s and 1980s) excavations intensified. It was then when the studies and conservation work carried out by the INAH were launched, which has allowed its secrets to be discovered.
Despite years of study, the archaeological institute trust in which there are still surprises: “Toniná still keeps many secrets that will have to be known.”
