The Tempel Synagogue is a synagogue in Kraków, Poland which was built in 1860 and was ruined during World War II by the German Nazis, who used the building as an ammunition storage area.
After the war, it was used again for prayers. In 1947, a mikvah was built in the northern part of the synagogue. It is still active today, although formal prayers are held only a few times a year. Wishing you all #ShabbatShalom!
