In the heart of Bulgaria’s karst landscape there is a cave that seems designed by someone with a sense of cosmic theater. It is called Prohodna, it measures 262 meters in length, and it has, in its ceiling, two perfectly oval openings that from below look exactly like what their name suggests: the eyes of God.
No one built them. Erosion carved them over millions of years until it gave them that shape which, when sunlight passes through them during the day, turns the inside of the cave into something difficult to classify as either natural or sacred. At night, the effect changes but does not diminish: the stars and the moon appear framed in each opening as if someone had cut the sky with surgical precision.
The cave is located near the village of Karlukovo and is one of the most photographed geological phenomena in the Balkans. Seeing it in an image is already impressive. Standing beneath those two eyes of rock, with the sky looking down at you from above, is a completely different experience.
