Old Synagogue is an Orthodox Judaism synagogue in Kazimierz, Kraków, Poland. It is the oldest existing synagogue in Poland and one of the most precious landmarks of Jewish architecture in Europe. Until the German invasion of Poland in 1939, it was one of the most important synagogues in the city as well as the main religious, social, and organizational centre of the Kraków Jewish community.
