In Turkish Zeliha is the "Su perisi" and the story is also told in the Holy books. Its in the same central area as the Abraham cave and waters so you really should not miss it.
The story of zeliha which is the story of the water fairy" which turned into a white fish. I understand this is also in the holy books within the story of Abraham.
A very nice pound, dedicated to the daughter of Nemrud and next to Balıklıgöl and just under the castle. Here you can have a drink and enjoy the views.
