A man from Derinkuyu, in the Nevsehir province of Turkey was renovating his basement. Using only a sledgehammer, he broke through one of his walls; and felt cool air coming in from the other side. Inside he found a small room-sized cave. This area of Turkey has complex cave systems so he thought he accidentally stumbled into one. He didn't. That first small room -- was only the beginning.
