The Wolf Popper Synagogue (Polish: Synagoga Poppera, or Synagoga Bociana), located in Kraków, Poland, used to be one of the most splendid Jewish houses of prayer in the old Jewish quarter of Kazimierz established in a suburb earmarked in 1495 by King Jan I Olbracht. The Synagogue was founded by Wolf "The Stork" Popper in early 17th century. Its entrance was once adorned with openwork doors depicting four animals: an eagle, a leopard, a lion, and a buck deer, which symbolize the main traits of a devout man. The synagogue, featuring porches, annexes, Aron Kodesh, rich furniture and decorations, went into a decline not long after the passing of its founder and chief benefactor. At present, Popper Synagogue serves as the youth community centre with a strong accent on programs and workshops exploring the coexistence of Polish and Jewish cultures.
