Known locally as the Cave of the Crystal Sepulchre, ATM Cave is heralded as one of Belize’s most exceptional archaeological and natural wonders. The name translates to “Cave of the Stone Sepulchre” in the ancient Maya language. This cave has gained international acclaim for its abundance of ceremonial Maya artifacts and is particularly famous for housing the calcified skeleton identified as the “Crystal Maiden.”

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

The entrance of the ATM Cave was first ventured by the ancient Maya around 300–600 AD; however, it was between 700–900 AD that significant ceremonial practices flourished. For the Maya, caves like ATM were revered as spiritual portals to Xibalba, the underworld, where vital rituals were conducted to petition for rain, fertility, and divine favor from their deities.

• “Kill holes”: Many of the pots discovered within the cave feature intentional piercings designed to liberate their spirits, thereby allowing them to transition to the Underworld.
