Passages of Derinkuyu
The most mysterious and evocative thing about Derinkuyu underground city is its narrow, winding passageways. You never know where you'll end up. Often the passage just get very narrow or branches into several, or ends in a round stone door bolted closed. Now with tourism, most of the corridors are lit, but it does not take much to imagine a time when the troglodytes only had a torch to guide them in this maze of passageways and stairs going up and down. The perfect place for a horror movie!
