Temple of the Feathered Serpent: mass burial and ritual tunnel discovered. Over 200 people were buried inside the structure, many bound and wearing military-style uniforms They were arranged in deliberate symmetrical patterns—this was organized burial built into the monument's foundation Beneath the pyramid, a tunnel sealed for roughly 1,800 years was reopened in the early 2000s

Beneath Teotihuacan's Temple of the Feathered Serpent, archaeologists uncovered a vast tunnel system containing over 200 individuals buried in deliberate symmetrical patterns—some bound, suggesting ritual sacrifice tied to the monument's foundation. A tunnel sealed for roughly 1,800 years held jade figurines, carved shells, pyrite spheres, and other offerings. Pyrite dust coating the tunnel walls would have made torch light glitter brilliantly—like stars in an underground cosmos. This recreated the Mesoamerican underworld, where souls had to cross rivers to reach the realm of the dead. The nearby Pyramid of the Sun also sits directly over a cave, serving as a gateway between worlds. ⚱️✨
