1 Km Long Submerged Stone Age Wall Discovered Along German Baltic Coast

An around one-kilometre-long submerged wall of the Stone Age era was discovered along the German Baltic coast. According to scientists, this is the oldest known human-made megastructure in Europe, reported The Guardian. It is believed to have been constructed 11000 years ago.

The massive structure, now known as the “Blinkerwall,” was discovered during a student research trip. It was found 21 meters underwater. A sonar scan revealed the underwater wall formed of 1,400 smaller stones connected to 300 massive boulders.

The wall seems to be constructed by a large group of pre-historic humans. Some boulders in the wall are so big that it would have been impossible for individuals to move them. This hints at some advanced construction techniques even in the Stone Age.

According to The Guardian, experts believe the wall, was likely built on dry land around 11,000 years ago, possibly near a lake or marsh. Rising sea levels over thousands of years submerged the wall.

The reason for which this wall was constructed is being researched. It is believed that this wall may have been used as a trap to hunt large animals.
