Orlovi Skali, Megalith sanctuary in Ardino, Bulgaria.
Orlovi Skali is a rock sanctuary near the town of Ardino in southern Bulgaria, carved directly into a natural stone formation. The western face of the rock holds around 97 trapezoid-shaped niches cut into the stone, rising about 30 meters (98 feet) above the surrounding forest floor.
The site dates back to the late Bronze Age, when it was used as a sacred place for religious ceremonies, most likely by Thracian communities. Carvings were added over generations, pointing to a long period of active use rather than a single moment of construction.
The niches carved into the western face of the rock are trapezoid in shape and arranged in rows that follow the natural contours of the stone. Standing in front of them, visitors can see how deliberately each one was placed, with no two being exactly alike.
The site is reachable on foot from the center of Ardino, through a forested path that leads directly to the rock face. Sturdy shoes are a good idea, as the ground is uneven and can become slippery after rain.
Carved channels run between circular basins across the rock surface, forming a system that was likely used to direct liquids during ritual ceremonies. This network suggests that the people who made it had a working knowledge of how to control the flow of water through stone.
