The name translates to “Cave of the Stone Sepulchre” in the Maya language, signifying its deep cultural roots. This cave is internationally renowned for its abundance of ceremonial Maya artifacts and, most notably, for housing the calcified skeleton known as the “Crystal Maiden,” which has captivated the interest of archaeologists and visitors alike.

Delve into the Intriguing History and Spiritual Importance of the Maya and ATM Cave

The entrance of ATM Cave was initially discovered by the Maya around 300–600 AD; however, it was during the period of 700–900 AD that substantial ceremonial activities were observed. For the Maya, caves like ATM were revered as spiritual portals to Xibalba, the underworld, where vital rituals were conducted to invoke rain, fertility, and the goodwill of their deities. These spiritual practices highlight the cultural significance of the cave as a sacred site.

• Sacrifice site: Archaeological investigations have unveiled at least 14 human skeletons, comprising both adults and children, alongside numerous ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: A number of pots discovered within the cave have been intentionally pierced to liberate their spirits, facilitating their transition to the Underworld.
• The “Crystal Maiden”: This remarkable skeleton, thought to be a young female, appears to radiate due to the build-up of mineral deposits accumulated over time[11][21].
