The discovering, close to the Toltec website Tula Chico in Hidalgo in central Mexico, was made throughout archaeological salvage work related to planning a brand new 232km passenger rail between Mexico Metropolis and Querétaro.
Development on the Mexico Metropolis-Querétaro practice started in April 2025, with official figures indicating that progress is at present at round 10%. This newest discovery resulted from INAH-led explorations alongside the route which have yielded colonial-era and Mesoamerican stays. “In preliminary fieldwork, we have now recognized 12 areas of archaeological curiosity, together with objects and monuments of various scales,” Víctor Francisco Heredia Guillén, INAH’s salvage undertaking coordinator, tells The Artwork Newspaper.
In October, the invention of petroglyphs on the El Venado archaeological website close to Tula de Allende in Hidalgo prompted an 8km rerouting of the rail line. “Because of the petroglyphs’ significance, the route was adjusted to protect them,” Heredia Guillén says. “Though the location was identified for the reason that Seventies, the petroglyphs—some believed to be prehistoric—have been lately recognized on a steep cliff.” At a press convention later that month, Mexican president Claudia Sheinbaum emphasised the world as a present-day sanctuary for Indigenous peoples.

Nonetheless, its future has but to be decided, because the practice’s route—positioned solely 600m from Tula’s archaeological website—should still be modified. Non-archaeological components, resembling neighborhood opposition, have additionally been a part of the equation.
“At this stage, the practice’s last proper of manner has not but been outlined,” Heredia Guillén says. “As soon as established, concerns shall be issued relating to this and different archaeological parts, with heritage preservation and the undertaking’s wants rigorously assessed.”
Just lately, the development of different trains within the area—most notably the brand new Maya Practice—has sparked each heritage and ecological controversy. These concerned within the Mexico Metropolis-Querétaro practice undertaking emphasise that thorough examinations are in place.
