The Day of Remembrance of Jewish Genocide in Latvia is observed on July 4 each year. This day commemorates the anniversary of the burning of the Great Choral Synagogue in Riga in 1941, a significant event during the Holocaust when the extermination of Jews in Latvia began shortly after Nazi Germany invaded the Soviet Union. On this day, solemn ceremonies are held throughout Latvia to honor the approximately 66,000 Latvian Jews who were killed during this tragic period. The Great Choral Synagogue was set ablaze with twenty Jews locked in its basement, marking a grim chapter in the history of the Jewish community in Latvia. Other synagogues were also destroyed, with only the Peitav Synagogue surviving. The observance serves as a poignant reminder of the atrocities faced by the Jewish population in Latvia during World War II.
