One of Bulgaria’s most interesting historical monuments is the Belogradchik Fortress. It’s located on the slopes of the Balkan Mountains, and the area’s phenomenal rock formations serve not only as natural protection but also as an integral part of the fortification itself.
It’s believed that these ancient rock formations were formed over a period of more than 200 million years, and they’ve now become unique obelisks, reddish sandstone castles, and oversized stone figures that soar high into the sky.
