Project Lyobaa created a 3D model of a system of caves and passageways known as the “backdoor to Hell” in southern Mexico.
The ancient Zapotecs believed the subterranean site to be an entrance to the underworld.
The location under a church matches local lore of where the entrance was all along.
In 1674, Francisco de Burgoa—a 17th century Dominican chronicler—gave an account of exploring subterranean temples containing four interconnected chambers with a group of Spanish missionaries.
They found tombs of priests and kings of Teozepotlan.
And then came the most intriguing—a stone door that led to a cavern as deep as 90 miles (yeah, we’re not sure how that’s possible either) into the Earth, complete with intersecting passages and a pillar-supported roof.
