Prohodna Cave
Prohodna Cave, famous throughout Europe for its two massive almond-shaped ceiling openings known as 'The Eyes of God' (Oknata), is a natural karst cave passage located in the Karlukovo Gorge of northern Bulgaria. Inhabited by humans since the Neolithic and Chalcolithic eras, this awe-inspiring 262-metre-long natural cavern has served as an ancient Thracian ritual sanctuary. When rain falls through the ceiling openings, water trickles down the limestone face like tears, giving rise to mystical legends of divine grief and ancient pagan spirits.
