The island of Santorini is believed to be the location of the lost city of Atlantis. According to the ancient Greek philosopher Plato, Atlantis was a powerful island nation that was destroyed in a single day and night of catastrophic earthquakes and floods. Some historians and archaeologists have speculated that Santorini, which was devastated by a massive volcanic eruption in the 2nd millennium BCE, could be the real-life inspiration for Plato's Atlantis legend. While there is no hard evidence to support this theory, it remains a popular topic of discussion and debate among scholars and enthusiasts.
