Józefa Street, which runs adjacent to Szeroka Street, was the main route connecting the Christian and Jewish parts of Kazimierz. It was named in honor of Emperor Joseph II of Austria, who once visited Kazimierz. The street has retained its historic charm—today, the ground floors of the buildings house antique shops, galleries, as well as numerous cafés and restaurants.
Following Józefa Street, we reach Kupa Street, which takes its name from the synagogue located at its end, built in the 16th century with funds from the kahal treasury (kupa meaning “treasury”). Originally constructed as a modest building, its northern wall still rests against the remnants of Kazimierz’s medieval wall. On the same street, we also find the beautiful Baroque Isaac Synagogue, founded by the wealthy merchant Izaak Jakubowicz.
