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

The entrance of ATM Cave was initially explored by the Maya around the years 300–600 AD. However, it was during the period spanning 700–900 AD that significant ceremonial activities occurred within its caverns. For the ancient Maya, caves such as ATM were viewed as sacred portals to Xibalba, the underworld, where crucial rituals were conducted to invoke rain, ensure agricultural fertility, and gain favour from their deities. This deep-rooted belief system underpins the cultural importance of such sites.

“Kill holes”: Many pots discovered within the cave have been deliberately pierced to release their spirits, facilitating their transition into the Underworld, demonstrating the Maya belief in the afterlife.
The “Crystal Maiden”: This iconic skeleton, identified as a young female, appears to shimmer due to the accumulation of mineral deposits over time, creating a striking visual effect that captivates visitors[11][21].
