Throughout history, entire cities have vanished, leaving behind only myths and legends to explain their demise. From the biblical city of Sodom, destroyed by fire and brimstone according to the Bible, to Doggerland, a Mesolithic paradise lost beneath the waves of the North Sea, and Helike, a classical Greek city that disappeared in 373 BCE, these ancient civilizations were all wiped out by catastrophic events. But were these stories purely myth, or is there evidence of their existence? Archaeologists are uncovering clues in modern-day Jordan that may reveal the location of Sodom, and under the sea, the remains of Doggerland and Helike are being pieced together to tell the stories of the people who lived there and their struggles against nature’s wrath. Could Helike even be the inspiration behind the legendary Atlantis? The mysteries of these lost worlds continue to captivate and challenge us, as archaeology and science bring their forgotten pasts to light.
