Photo taken on Jan. 27, 2019 shows the wall of the Old Jewish Cemetery in Frankfurt, Germany. The 286-meter-long wall contains more than 11,900 small steel blocks, which recorded the names of Frankfurt's Jews deported and murdered between 1933 and 1945. In 2005, the UN General Assembly adopted a resolution which designated Jan. 27 as the International Day of Commemoration in Memory of the Victims of the Holocaust, the day when Auschwitz death camp was liberated in 1945.
