Lost World Discovered: 11,000-Year-Old Hunting Structure Found Beneath Baltic Sea

Archaeologists have uncovered a remarkable 11,000-year-old megastructure hidden beneath the Baltic Sea, believed to be one of the oldest known man-made hunting structures in Europe. Dubbed the “Blinkerwall,” the structure consists of a 1-kilometre-long arrangement of nearly 1,700 stones, carefully placed in a linear pattern about 21 metres below the sea surface between Germany and Sweden.
Experts believe the structure was built by Mesolithic hunter-gatherers around 9,000 BCE and was likely used as a sophisticated tool for hunting reindeer, guiding them into traps or ambush zones. Its strategic placement suggests humans had deep knowledge of animal behaviour and migration routes.
The discovery was made accidentally during a sonar survey of the seafloor by researchers from Kiel University and the Leibniz Institute for Baltic Sea Research. The stones are too large and uniformly placed to be a natural formation, reinforcing the conclusion that this was an intentional prehistoric construction.
This submerged find offers a rare glimpse into early human ingenuity and adaptation after the last Ice Age, at a time when the landscape was still exposed and shaped by retreating glaciers. Scientists describe it as a “sensational discovery” that opens new avenues in understanding early European societies.
