Divers, working with academics from the University of St Andrews, have discovered Doggerland (named after Dogger bank).
The research shows that a landmass once existed under the North sea that stretched from Britain to the continent. Around 20,000 years ago it reached a maximum but was mainly covered by ice and as the ice melted the land slowly vanished beneath the waves.
Research suggests that these drowned lands could have been home to tens of thousands of people and once might have been the real heartland of Europe.
Could it have given rise to the myths of Atlantis? Perhaps not. But the sunken land is subject of an exhibition at the Royal Society over this coming week.
