Delve into the Rich History and Spiritual Significance of the Maya and ATM Cave

The entrance of the ATM Cave was first explored by the Maya around 300–600 AD. However, it was during the period from 700–900 AD that significant ceremonial practices flourished within its depths. For the Maya, caves such as ATM were regarded as spiritual gateways to Xibalba, the mythical underworld, where vital rituals were performed to invoke rain, promote fertility, and seek favour from their deities.

Sacrifice site: Archaeological excavations have revealed at least 14 human skeletons, including both adults and children, alongside numerous ceremonial pots, obsidian blades, and grinding stones[15][11].
“Kill holes”: Many pots discovered within the cave have been intentionally punctured to release their spirits, facilitating their passage to the Underworld.
The “Crystal Maiden”: This iconic skeleton, believed to be a young female, appears to glimmer due to the accumulation of mineral deposits over centuries[11][21].
“Monkey Pot”: A distinctive and rare ceramic vessel, one of only four found throughout Central America[11].
