Across the world, entire cities have slipped beneath lakes, seas, and marshes. Some were destroyed by earthquakes, floods, or rising water, while others were deliberately submerged. Archaeologists have uncovered streets, temples, and homes, but many secrets remain hidden. These underwater ruins offer fascinating glimpses into civilizations we still barely understand today.
#1: Saeftinghe, the Drowned Dutch Town
Saeftinghe was a prosperous settlement in what is now the border region between the Netherlands and Belgium. After a major flood in 1570 and military flooding during the Eighty Years’ War, the town disappeared into marshland. Archaeologists still have not located its remains, and shifting tides make the surrounding Drowned Land of Saeftinghe difficult to explore safely.
