The name translates to “Cave of the Stone Sepulchre” in the Maya language. This cave is world-renowned for its wealth of ceremonial Maya artifacts and, most notably, for housing the calcified skeleton known as the “Crystal Maiden.”

Unveiling the Rich History and Spiritual Significance of the Maya & ATM Cave
The entrance of ATM Cave was first explored by the Maya around 300–600 AD, but it was between 700–900 AD that significant ceremonial activities took place. For the Maya, caves like ATM were considered spiritual gateways to Xibalba, the underworld, where important rituals were performed to invoke rain, fertility, and the favor of their deities.
- Sacrifice site: Archaeological excavations have revealed at least 14 human skeletons, including both adults and children, alongside hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
- “Kill holes”: Many pots found within the cave are intentionally pierced to release their spirits, allowing them to transition to the Underworld.
- The “Crystal Maiden”: This iconic skeleton, believed to be a young female, appears to shimmer due to the accumulation of mineral deposits over the years[11][21].
- “Monkey Pot”: A distinctive and rare ceramic vessel, one of only four found in Central America[11].
