Stolpersteine (stumbling stones) is a project of the artist Gunter Demnig. The project commemorates people who were persecuted by the Nazis between 1933 and 1945. Stolpersteine are being realized for Jews, Sinti and Roma, people from the political or religious resistance, victims of the “euthanasia”; murders, homosexuals, Jehovahs Witnesses and for people who were persecuted for being declared to be “asocial”.The concrete blocks measuring 10x10cm and are laid into the pavement in front of the last voluntarily chosen places of residence of the victims of the Nazis. Their names and fate are engraved into a brass plate on the top of each Stolperstein. For more than 20 years they have been part of the urban image of Berlin. Thus, the exhibition wants to introduce the often unknown groundwork and manifold facets of this European art and remembrance project. Those participating in the origination process as well as those later walking by are presented as part of this social sculpture.
