It is the Memorial for the eastern German Homeland (Mahnmal für die ostdeutsche Heimat), an 8 meters cross of pine wood with a crown of thorns of barbed wire, located on the upper edge of the Kreuzberg's sodded northwestern slope, and commemorating the deaths of 100,000s killed in atrocities, by forced labour or other maltreatment, and the fate of the surviving 12 million refugees and expellees from former eastern Germany and neighbouring foreign countries ruled after World War II by pro-Soviet governments.
