“Stumbling stones” (“Stolpersteine” in German) is an international project to honor the memory of the victims of Nazism. Its idea is to install a memorial “stone”, a small metal plaque with information about a person who died at the hands of the Nazis or survived despite persecution. “Stolpersteine” are placed near this person’s last place of residence, work, or study, so that passers-by would metaphorically “stumble” over it and stop for a moment, thinking about the person who once lived here.
