5. Atlantis City

The most enigmatic archaeological discovery ever made by scientists is the lost city of Atlantis. Plato was the first individual who told the story about Atlantis City and how it disappeared from the surface of the planet and sank in the ocean. Researchers claim that the tragedy was caused by a strong tsunami that hit Atlantis in the 10th millennium B.C. However, the truth is unknown. Atlantis is believed to be built by the God of sea named Poseidon. The city was incredibly beautiful and rich. Archeologists are still trying to spot the actual location. Some say it is somewhere close to the Atlantic Ocean. Since the ocean is deep, it prevents researchers from further research and exploration.
