Underwater divers recently discovered paved floors, courtyards and colonnades, evidence of a long-forgotten civilization that must have perished when tidal waves hit the shores of the Greek holiday island Zakynthos.
The bizarre discovery, found close to Alikanas Bay, was carefully examined in situ by the Ephorate of Underwater Antiquities of Greece. After the preliminary mineralogical and chemical analyses, a research team was mobilized to study the ancient underwater remains - only to declare them a naturally occurring phenomenon created by a natural geological phenomenon that took place in the Pliocene era, up to five million years ago.
