Lost Civilizations: The 3 Underwater Cities That Rewrite History (Yonaguni, Heracleion, Pavlopetri)

Dive deep into the mystery of the lost worlds beneath our waves. We explore three incredible underwater cities—Yonaguni, Thonis-Heracleion, and Pavlopetri —that are forcing historians to rewrite ancient history. From civilizations swallowed by rising sea levels to cities dragged under by massive tectonic shifts , the oceans hold secrets far stranger than fiction. Trust us, you will look at the ocean differently after this video!

What You'll Discover:

The Mystery & The Science: How massive sea level changes (up to 400 feet lower 20,000 years ago) and terrifying geological events caused entire ancient coastlines to vanish underwater. * Yonaguni Monument, Japan: The highly controversial underwater rock formation that some believe is a man-made monument from an ancient civilization, potentially older than many Roman ruins. * Thonis-Heracleion, Egypt: The legendary gateway to Egypt and major port city that vanished by the 8th century AD —its discovery rewrote what we knew about ancient Egyptian trade. * Pavlopetri, Greece: Explore the oldest submerged city ever found, dating back over 5,000 years to the Bronze Age, with an incredibly preserved urban layout of streets and courtyards.

We also look at the new technology transforming marine archaeology and the race to document these sites before they are lost forever.
