Explore the Deep Historical Roots and Spiritual Significance of the Maya in ATM Cave

The entrance of ATM Cave was first explored by the Maya around 300–600 AD, but it was during the period from 700–900 AD that significant ceremonial activities took place. For the Maya, caves like ATM were considered spiritual gateways to Xibalba, the underworld, where essential rituals were performed to invoke rain, fertility, and the favour of their deities. This belief system underscores the cave's importance in the context of ancient Maya culture and its connection to their spiritual practices.
