Explore the Deep-Rooted History and Spiritual Significance of the Maya and ATM Cave

The entrance of ATM Cave was first discovered by the Maya around 300–600 AD, but it was during the period between 700–900 AD that significant ceremonial activities were conducted. For the Maya, caves like ATM were revered as spiritual gateways to Xibalba, the underworld, where essential rituals were performed to invoke rain, fertility, and the favours of their deities. This belief system underscores the cave’s profound cultural and historical importance.
