Hunebeds - Huenenbetten ,Huenengraeber is the German name for a large number of megalithic stone grave sites , large bolder stones set in formation around burial sites.Huenenbetten bolders were and are still remaining by the thousands in northern Europe all along the Baltic Coast lands .
Bolders were used partially underground to create chambers . Therefore also called chamber graves. A huge semi square , somewhat flat bolder was laid on top , for cover , giving it a mushroom-like apperance . In Mecklenburg and Pomerania large numbers of these graves were disturbed , when towns and cities were built . The bolders came in handy for construction and road building . There are still many left today , even with the extreme density of population in Germany and all over Europe . An earlier list of Hunebeds (Huenenbetten) in northern Germany, made by a landowner , showed over 1000 hunebeds at that time. I believe that was on Ruegen? , an island in the Baltic Sea , off northern Germany.
