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

The entrance of ATM Cave first attracted the attention of the Maya between 300 and 600 AD. However, it was during the period spanning from 700 to 900 AD that substantial ceremonial activities occurred within its depths. For the Maya, caves like ATM were perceived as spiritual gateways to Xibalba, the underworld, where vital rituals were conducted to invoke rain, ensure agricultural fertility, and seek favour from their deities.

Sacrifice site: Archaeological investigations 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”: Several pots discovered within the cave have been intentionally pierced to release their spirits, aiding their transition to the Underworld.
The “Crystal Maiden”: This iconic skeleton, presumed to be a young female, appears to shimmer due to the accumulation of mineral deposits accrued over time[11][21].
“Monkey Pot”: A unique and rare ceramic vessel, one of only four identified across Central America[11].
