In the heart of Belize, there is an ancient Mayan temple that holds thousands of secrets. The Actun Tunichil Muknal (ATM) is hiding something that thousands of people flock to see each year.

First explored in the 1980s, the ATM gives us a glimpse into what life was like when Mayan culture was in its prime. The Crystal Maiden is its most famous treasure.

The Crystal Maiden is the skeleton of a woman in her twenties who was sacrificed as part of a ritual.
