Researchers report an astonishing find in the Baltic Sea: Apparently there are indications of further discoveries. Stone wall is 971 meters long and is located ten kilometers from Rerik on the southwestern edge of the marl ridge in a water depth of 21 meters on the bottom.
The structure consists of 1,673 stones the size of tennis or football, which are connected by a few large boulders to form a wall up to one meter high. The wall must have been built before the water level rose sharply after the last ice age. Around 8,500 years ago large parts of the previously accessible landscape were flooded.
