A Stone Age wall has been discovered in Germany’s Baltic Sea, stretching for about a kilometer along the ocean floor and believed to be the oldest megastructure built by humans in Europe.
The serendipitous discovery occurred while the scientists were operating a multibeam sonar system about 10 kilometers offshore in Mecklenburg Bay during a student trip. guardian report.
It is made up of 1,673 stones, each too heavy for humans to move, less than a meter high and spanning a distance of 971 metres.

Are Stone Age walls natural?
Researchers believe that the size and shape of the 971-meter wall makes it unlikely that it was formed by natural phenomena such as tsunamis or glacier movement.
“We think a coastline affected by ice floes is unlikely, but eskers, moraines, and tsunami deposits seem very unlikely. Finally, natural processes “There was one observation that could not be explained at all, which suggested a possible anthropogenic origin of the structure,” the researchers wrote. Proceedings of the National Academy of Sciences.
This is the preferred location for the largest and heaviest stones at knick points along the Brinker Wall, they added.

Were Stone Age walls man-made?
Researchers say they were built by hunter-gatherers on land near lakes and wetlands more than 10,000 years ago. Although its exact purpose is difficult to prove, scientists suspect that the wall served as a hunting route for reindeer herds. The animals may have been lured by intentionally creating an artificial bottleneck, perhaps at the second wall or the lakeshore.

A second wall, possibly buried in seafloor sediments, or the blinker wall itself may have funneled animals into nearby lakes, slowing down effective hunting. Although reindeer can swim, water would have hindered their progress and made them easy targets for hunters in canoes armed with spears and bows and arrows. If the wall was an ancient hunting trail, it may have been submerged by rising sea levels about 8,500 years ago.
Brinkerwall’s suggested date and functional interpretation make this a thrilling discovery, providing valuable insight into the survival patterns of early hunter-gatherer societies and shedding light on human history more than 10,000 years ago. , the researchers added.
