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

The entrance to ATM Cave was first explored by the Maya around 300–600 AD. However, it was during the period from 700–900 AD that substantial ceremonial practices were conducted within its depths. For the Maya, caves like ATM were viewed as spiritual gateways to Xibalba, the underworld, where crucial rituals were performed to invoke rain, ensure fertility, and seek favour from their deities. This sacred connection to the land and the cosmos reveals a profound understanding of their environment and spirituality.

Sacrifice site: Archaeological excavations have unearthed 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 have been deliberately pierced to release their spirits, facilitating their transition to the Underworld.
The “Crystal Maiden”: This iconic skeleton, believed to belong to 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 discovered across Central America[11].
