Fairy Chimneys in Cappadocia

Peris are the good faeries from Middle East, they are beautiful winged females with golden hair, bright eyes and pale skin. Persian tradition says that they are fallen angels who have to do penance on Earth, but they really live in Paristan, Middle East Fairyland. If you want to see a peri in the realm of mortals you should go to the valleys of Cappadocia, where there are a lot of conical rock formations called by humans "Peri bacalari" (fairy chimneys), due to peris live inside them.
These rock formations consist of a layer of tuff (consolidated volcanic ash) covered by a more resistant layer of volcanic rocks; erosion caused cracks in the covering layer, allowing to wind and water sculpt the tuff layer and give these chimney and mushroom like forms. And you know that faeries love these natural forms.
But it will be hard to see a peri there, because many of these fairy chimneys were occupied and turned into rupestral churches by early christians, who also started to say that peris were fallen angels born of Satan. So I don't think that peris were anxious to see humans...

Thanks to David Riche for tell me about the Peri Bacalari; this article born in David's mind, I'm just the scribe.
