Ancient Art Found Thanks to Mexico Train Project

Sixteen ancient cave paintings and rock carvings have been discovered at El Venado archaeological site in Hidalgo, Mexico, thanks to careful planning during the construction of a new passenger train between Mexico City and Querétaro.

The artworks date back nearly 4,000 years, stretching from prehistoric times through the era of the Toltecs and Aztecs. Archaeologists found them in January during rescue archaeology work along the train route near the Tula River and La Requena Dam.

The discovery site got its name decades ago when renowned Mexican archaeologist Eduardo Matos Moctezuma first uncovered a painting of a deer there in the 1970s. Since then, the area has revealed images of regional animals, natural phenomena, and human figures.

The newly found paintings include striking depictions of humans wearing headdresses, carrying shields, and wielding weapons. One figure sports accessories linked to Tláloc, the ancient Mexica god of rain, while another shows a face adorned with ornaments and painted in red with white stripes.

Time has faded some images, but researchers can still make out a stylized human figure in red and shapes that might represent a snake or lightning. One particularly intriguing piece shows a human face combined with bird or horse legs, suggesting it was created around the time Spanish colonizers arrived.

The Bright Side

This discovery almost didn't happen. President Claudia Sheinbaum announced last year that the original railway route would shift by eight kilometers specifically to protect the archaeological area where these paintings were found.

That decision transformed potential destruction into preservation and discovery. The rescue archaeology program, required for infrastructure projects in Mexico, turned construction into an opportunity for understanding the past.

Researchers are now comparing these artworks with similar discoveries throughout the region. The findings show that this sacred site remained culturally significant for thousands of years, even into the early colonial period when indigenous and Spanish cultures collided.

These ancient voices, preserved on cliff faces near the water, now get to tell their stories instead of being buried under steel and concrete.
