The Ancient Mayans believed cenotes were sacred. Cenote comes from the Mayan word “dzonot” which means “sacred well.” A cenote is a sinkhole in the surface formed over time from water on porous limestone, leaving underground caves and caverns. Cenotes were the main source of fresh water for the ancient Mayans. They believed the cenotes contained curative elements, and believed cenotes to be portals to communicate with the gods.
