The Prohodna cave in Bulgaria amazes tourists from all over the world with its unusual appearance. The most famous part of this cave, which is about 262 meters long, is two huge eye-shaped holes in its ceiling.
These holes, formed by the action of water and wind over thousands of years, are popularly called the “Eyes of God”. During the day, sunlight enters the cave from these places, creating a very mysterious and impressive view.
At night, the moon and stars are visible through the holes, making the cave resemble a scene from a fantasy film. That is why the Prohodna cave has become one of the most popular attractions in Bulgaria.
