Sensational find in the Baltic Sea: Mysterious stone wall from the Ice Age discovered. The structure consists of 1,673 stones the size of a tennis ball or football, which are connected by a few large boulders to form a wall up to one meter high.
The stone structure is 971 meters long and lies ten kilometers from Rerik on the southwestern edge of the marl ridge in a water depth of 21 meters on the seabed. According to the current knowledge, the wall must have been built before the water level rose sharply after the last ice age.
