A #stoneage wall stretching for nearly a mile over the seabed in the Bay of Mecklenburg at the bottom of #BalticSea may by the oldest "#megastructure" in #Europe. Named the #Blinkerwall, it rests under about 70 feet of water and the best guess is that it was constructed by hunter-gatherers by a lake or marsh in about 8,000 B.C.
