Eyes of God cave, Bulgaria

Eyes of God cave, Bulgaria
Located in the Iskar Gorge amidst one of Bulgaria’s largest karst regions, Prohodna is one of the best-known caves in a country full of them. This is thanks in large part to the eerily symmetrical holes in the cave’s ceiling, which provide visitors with a rather striking subterranean image. Known as the Eyes of God, these holes are located in the middle chamber of the 262-meter-long cave, illuminating the interior and providing a uniquely framed view of the firmament above. Remarkably in size, similar in shape, and eyeish in appearance, these holes are the result of natural erosive forces. (The possibility of human embellishment has not been ruled out). These slow and steady forces are still at work, as is often demonstrated by the water running down the cave walls from the “crying” eyes above.
