Now a tiny fishing village with only over a 100 people, Dunwich was once the 10th largest city in England almost as big as London today.

By the 15th century the once thriving city with its cathedrals, houses, and port structures was washed under water.
6. Doggerland, North Sea
In ancient times, the Doggerland was home to Mesolithic tribes in the North Sea. Now a mere speck, once they were a continuous mass of land joining England with Europe about 20,000 years ago. Historians call the Doggerland the north's Garden of Eden where life (both human and animal) was on its full swing, until the sea level started rising and swallowed large chunks of the land masses. Before the flooding, Doggerland was largely occupied with fishermen and hunters.
