Researchers at Germany’s Kiel University discovered a 10,000-year-old wall in the depths of the Baltic Sea. Made of 1,670 stones, this megastructure was found around 9.7kms off the coast of Germany’s Rerick. The wall is situated approximately 69ft below water and stretches for around 1km. It comprises large boulders that were connected using many small stones and is believed to have been built by Stone Age communities. This structure was used by Stone Age hunters to hunt reindeer in ancient times and may be Europe’s oldest megastructure constructed by humans, according to researchers.
