In Puebla, Mexico, buried beneath centuries of earth and mystery, lies the Great Pyramid of Cholula—the largest pyramid by volume in the world. But its true wonder isn’t just its sheer size… it’s what lies beneath.

Winding through the heart of this ancient behemoth is a network of tunnels stretching for kilometers, a forgotten passage into the past. Discovered in the early 20th century, these corridors whisper secrets of a civilization that built, expanded, and transformed this sacred structure over countless generations.

Each tunnel tells a story—of power, devotion, and an ever-evolving monument to the gods. What rituals took place in its depths? What knowledge remains hidden within its ancient walls?

One thing is certain: Cholula is more than just a pyramid—it’s a time capsule of Mesoamerican history, waiting to be fully uncovered.
