She added, "Unfortunately, later on German history developed in an even more dramatic way which eventually ended in the Shoah" or Holocaust. The chancellor also called on Germans to never forget the past.
Across Berlin, guided groups of residents walked through their neighborhoods, noting sites where Jewish stores, schools and other locations once stood before being destroyed by the Nazis and their supporters.
Several Berliners came together to polish some of the city's 5,000 Stolpersteine, or stumbling blocks, which identify by name individual victims of Nazis in front of their former homes. The cobblestone-sized brass plaques are inserted on sidewalks and called stumbling blocks because one unexpectedly trips over them figuratively speaking while strolling through the city.
"We have organized 16 groups who are out today cleaning the stumbling blocks and we are hoping to turn this into an annual event in the future," said the coordinator of the tours, Silvija Kavcic.
Despite the many positive activities, some speakers sounded a note of caution, reminding their listeners that anti-Semitism is still a problem in Europe.
A poll of European Jews released Friday found that more than three-quarters of those questioned believe anti-Semitism is surging in their home countries and close to one-third have considered emigrating because they don't feel safe.
