Uncover the Rich History and Spiritual Significance of the Maya and ATM Cave

The entrance of ATM Cave was first explored by the Maya between 300–600 AD. However, it was during the period from 700–900 AD that substantial ceremonial practices were conducted within its extensive interior. For the Maya, caves like ATM were viewed as spiritual gateways to Xibalba, the underworld, where critical rituals occurred to invoke rainfall, ensure agricultural fertility, and seek favour from their deities.

Sacrifice site: Archaeological excavations have revealed at least 14 human skeletons, including those of 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 pierced to release their spirits, facilitating their transition to the Underworld.
The “Crystal Maiden”: This iconic skeleton, thought to be a young female, appears to shimmer due to the mineral deposits that have accumulated over the years[11][21].
“Monkey Pot”: A unique and rare ceramic vessel, one of only four discovered throughout Central America[11].
