Capadoccia's fairy chimneys were home to persecuted Christians and now house tons of tourists. Nearby, there are several underground cities that used to be inhabited by Christians--some up to 8 stories deep into the sandstone. Teeny tiny rooms are stacked one atop the other and connected through tortuous pathways. I was feeling pretty claustrophobic when I peered up the ventilation shaft and saw how far down we were!

Large cave complexes
Many are now cushy cave hotels.
