Doggerland was an area of land, now lying beneath the southern
North Sea, that connected
Great Britain to mainland
Europe during and after the
last Ice Age. It was then gradually flooded by rising sea levels around 6,500–6,200 BCE. Geological surveys have suggested that it stretched from Britain's east coast to the
Netherlands and the western coasts of Germany and the peninsula of
Jutland. It was probably a rich habitat with human habitation in the
Mesolithic period, although rising sea levels gradually reduced it to low-lying islands before its final destruction, perhaps following a
tsunami caused by the
Storegga Slide.
