00:00 Plato's mention of Atlantis was likely allegorical and not based on a real place.

04:26 Plato's description of Atlantis sinking into the sea in a single day and night of misfortune has led to various theories and claims about its location, ranging from the Strait of Gibraltar to the Azores, Egypt, Peru, and even Switzerland, but these claims are unfounded and have turned the search for Atlantis into a topic embraced by fringe dwellers.

08:26 The city of Heliki in ancient Greece, which was a powerful city and the center of the Achaean League, suffered a fate similar to Atlantis when it was submerged by an earthquake and enormous wave overnight, with no survivors.

12:45 The city of Heliki was submerged and covered up over the centuries due to an earthquake, tsunami, and the deposition of silt from three rivers, making it a unique and well-documented example of a lost city.

16:45 Archaeologists discovered six other distinct occupied horizons beneath the city of Heliki, including a Byzantine period, a Roman ruin, a settlement from the Bronze Age, and possibly a prehistoric Neolithic civilization.

21:10 The idea that rising sea levels have caused coastal cities to become underwater has led archaeologists to search for human habitation underwater, such as the submerged area off of Wales called Doggerland where Neolithic settlements have been found, supporting the possibility of a lost city like Atlantis.

25:04 Archaeologists have found buildings, industrial buildings, kilns, looms, intersecting streets, coins, jugs, and a seawall from the Bronze Age in the submerged area of Helike, suggesting the existence of a real city.
