This isn't about the hollow Earth theory or anything like that, but about a real place that is pretty amazing in it's size and it's construction!
Stepping away from fiction for a moment is the curious case of the underground city known as Derinkuyu. Located 76 meters (250 ft) below the Earth’s surface, its earthwork walls and buildings descend deep into the ground and span 18 floors. While many modern edifices and structures can dig deep into the recesses of the Earth, having an ancient variation on this idea traverse such subterranean depths is truly an astounding feat of ingenuity and versatility.
Of course, all of this raises the question of “Why?” Unfortunately, little is known about Derinkuyu and its enigmatic ancient inhabitants. While the origin of this city may never be known, the fact that it still stands and can accommodate up to 20,000 people shows just how impressive these ancient Turkish builders truly were.
As is often the case with an article like this, we come away with more questions than answers. That is what makes it so interesting, ya see?
