Caves are supposed to be dark passages with narrow openings and sharp rock formations like stalactites. Prohodna cave in Bulgaria is not like that at all. The cave is only 260 meters long, with unusually tall entrances on both ends. The result is that the cave is not dark at all. Rather, the tall ceilings, indirect light, and lack of stalactites make it resemble a cathedral more than a cave. Indeed, the cave has been used for worship in its history, and many legends have grown up around it.
Prohodna cave has also been used in the past for imprisonment, and for hiding treasure. Now it is a popular tourist site and a draw for bungee jumpers. Many visitors report feeling spiritual as they walk through the legendary cave, especially when they see its most notable formation- two natural skylights, which are called "the Eyes of God." They are something you have to see to believe, so go to Kuriositas to see and read about those "eyes" in Prohodna cave.
