High in the rugged Caucasus mountains, scattered stones once seemed like little more than the remains of a forgotten hilltop ruin. For years, archaeologists walking the slopes saw only fragments, walls barely rising above the earth and hints of structures lost to time. But when researchers began scanning the landscape from above, the picture changed dramatically. Drone imagery stitched thousands of photographs into a detailed map that revealed something far larger beneath the surface. Hidden outlines of walls, settlements, and defensive structures began to appear. What once looked like a modest outpost is now emerging as a vast fortress complex built nearly three thousand years ago.
