It’s happened again, another monolith has disappeared. Following in its Utah counterpart’s footsteps, the Romanian monolith has suddenly vanished. 

The monolith was placed near an ancient Dacian Fortress dating back to B.C. times. Now only a shallow, rubble-holding, square-shaped hole is the only thing that remains of the structure, as seen in a video posted by Journal FM.
