Top 10 Most disturbing unexplained mysteries in the world (With Pictures)

9. The Baltic Sea Anomaly

In June 2011, divers from the Ocean X Team, a Swedish-based salvage group, were searching the Baltic Sea when they came upon a fascinating formation which has since been dubbed The Baltic Anomaly.

This anomaly is a 197 ft. (60 meters) diameter circular rock-like formation on the ocean floor, at a depth of 275 ft. (85 meters). It rests on a tall pillar and has a structure similar to a staircase, leading to a dark hole. The anomaly rests at the end of what resembles a 980 ft. (300 meters) skid mark, or “runway.”

Some speculate it is a vintage World War II structure, a sunken relic, or even a downed flying saucer. We can only wait for a more in-depth investigation.
