Archaeologists discovered the Blinkerwall, a 1km-long low wall made of over 1,500 granite stones submerged below the Baltic Sea, possibly constructed by Palaeolithic people for hunting reindeer.
The Blinkerwall's human-made origin was confirmed by an archaeological diving team, noting its regularity, composition of large boulders and smaller stones, likely collected from the nearby area.
