Wall more than 10 thousand years old found in the Baltic Sea, Stone Age humans had built it for this reason

Within the Baltic Sea is a kilometre-long stone wall that dates back over ten thousand years. In 2021, while mapping marine sediments, this ancient structure was found.

Now scientists have concluded that Stone Age humans probably built this wall to hunt reindeer. Recently this report has been published in 'Proceedings of the National Academy of Sciences'.

This Stone Age structure is at a depth of 21 meters in the sea near the Gulf of Mecklenburg, Germany. It counts a total of 1,673 stones, which are less than a meter in height. These stones are lying side by side in an area about one kilometre long. Scientists believe that this is not natural.

Researchers speculate that this wall might have been constructed by hunter-gatherers in the Preboreal period. The Preboreal era is defined as the time between 10,200 and 8,000 years ago. The first saltwater to enter the Baltic Basin occurred during this time. The Atlantic Ocean includes the Baltic Sea. A very thick covering of ice formerly blanketed the region that is now the Baltic Sea.

Situated in the southwest region of the Baltic Sea lies the Gulf of Mecklenburg. This area has seen much research in recent decades to comprehend the composition and form of the sea surface. One such mapping study yielded hydroacoustic data that provided information on this old building. A team of researchers has reached the depths of the sea for further investigation.
