Scientists have discovered a “giant megastructure” under the Baltic Sea

A remarkable discovery has been made in the Baltic Sea: a huge structure that could be the oldest Stone Age megastructure built by humans in Europe. This blog post will tell you everything you need to know about this amazing find and what it reveals about the ancient people who lived there.

The structure, which has been named the Blinkerwall, is located 21 meters below the water surface in the Bay of Mecklenburg. It is composed of 1,673 individual stones that form a wall measuring around 1km in length.

The stones are not randomly placed, but arranged in a deliberate pattern that suggests a human-made origin.

The Blinkerwall dates back to 10,000 years ago, when the area was part of a vast landmass called Doggerland that connected Britain and continental Europe.

Doggerland was inhabited by hunter-gatherers who exploited the rich resources of the land and sea. However, around 8,200 years ago, Doggerland was submerged by rising sea levels caused by melting glaciers.

So why did these ancient people build such a massive structure? According to archaeologists, the Blinkerwall was likely used as a hunting device to trap and kill reindeer. Reindeer were an important source of food, clothing and tools for the hunter-gatherers, and they migrated across Doggerland in large herds.

The idea behind the Blinkerwall was to create an artificial bottleneck that would funnel the reindeer into a dead end, where they could be easily slaughtered. The wall would act as a barrier that the animals would not try to jump over or go around.

“When you chase the animals, they follow these structures, they don’t attempt to jump over them,” said Jacob Geersen of the Leibniz Institute for Baltic Sea Research.

The archaeologists believe that there was a second wall or a lake shore that closed off the other end of the bottleneck, but they have not found it yet. It may still be hidden under the sediment or eroded by the waves.

However, they are confident that the Blinkerwall is not a natural formation, but a product of human ingenuity and engineering.

“This puts the Blinkerwall into range of the oldest known examples of hunting architecture in the world and potentially makes it the oldest man-made megastructure in Europe,” they wrote in their paper published in the journal Antiquity.

The Blinkerwall is a great example of how much history lies beneath the waves, waiting to be uncovered and explored.
