Explore 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. However, it was between 700–900 AD that significant ceremonial activities took place, marking this site as a pivotal location for spiritual practices. For the Maya, caves like ATM were viewed as spiritual gateways to Xibalba, the underworld, where crucial rituals were conducted to invoke rain, fertility, and the favour of their deities. This connection to the divine underscores the cave’s importance in their cultural and spiritual practices.

Sacrifice site: Archaeological excavations have uncovered at least 14 human skeletons, comprising both adults and children, alongside hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
“Kill holes”: Many pots discovered within the cave are intentionally pierced to release their spirits, facilitating their passage to the Underworld.
The “Crystal Maiden”: This iconic skeleton, believed to be a young female, shimmers 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].
