Cerje Cave, is located 14km from Nis. In their underground halls hides an unusual treasure. The city of Nis proudly carries the name “the city of fairies” or related forms that mean nymphs from a spring. The described interpretation has gained a great popularity, and nymphs or fairies are becoming a symbol of the city on the Nisava. Who were the fairies from Nis (Naissus, Nisos)? Slovenian legends do not tell us much about it. However, in ancient Greek legends, a legendary place of almost the same name, Nisa, appears.

The legendary Nisa was inhabited by nymphs called Nisijade, who are known to have been the nannies of the minor god Dionysus. It is believed that the Greeks tried to explain the foreign name of the imported deity Dionysus to them with the legend of Niš. Interpreting that this name means God from Nis, they set out in search of the place of his origin. The myth about the Cerje cave also says that the God of wine, Dionysus was hiding from the jealous wife Hera in this cave.
