For many people, the thought of something lurking in the dark, cavernous depths of the Earth is both thrilling and terrifying. While science might find civilizations and sprawling cities to be an unlikely development below ground, that hasn’t stopped plenty of modern myths and tales from sprouting up. If you count yourself among those enthralled with the possibility of a world below the surface, take a moment to read about some of the more fascinating and otherworldly tales surrounding other realms that might dwell within our own.

One strange tale involves the infamous and genocidal Nazi regime of Germany during World War II.
