a place consisting of 3 caves. Caves; Church Cave, Hellmagzi Cave and Ayazma Cave. All of them served as temples from a religious point of view. The most important among them is the Hellmagz. He also has a mythological story. The half-god, half-human Heracles (Hercules), the son of Zeus, is given 12 tasks, the last of which is difficult for him to enter hell and fight with a 3-headed dog. When Heracles completes this task, the region is given its name. The name Eregli comes from Heracles.
A Museum Card is required to visit the caves. The travel area is a little small. There is a relief of the dog and the Virgin Mary in the Hellmagzi Cave. But to see, you need to catch the right light in the right place.
