Isaac's Synagogue, built in the early Judaic-Baroque style, was opened in 1644, and was a gift to the city from a wealthy Jew, Izaak Jakubowicz. It is perhaps the most strikingly beautiful of the Kazimierz synagogues, decoratively endowed with arabesques and arches yet retaining a sober linearity, especially within. There is much to admire, not least the fragments of original wall scriptures. Rabbi Eliezer Gurary runs the place with a smile and is usually on hand to provide information to all comers. A shop inside sells kosher food, wine and sweets, Jewish calendars and other items.

Admission 5/3zł.
