In 1875 Nisan Bak, together with Rabbi Shmuel Mordechai Warshavsky and under the auspices of Kollel Volhin, founded the Jewish neighborhood of Kirya Ne'emana, initially called "Oholei Moshe vi-Yhudit" ("Tents of Moses and Judith"), but popularly known as "Batei Nissan Bak" ("Nissan Bak Houses"). The neighborhood was originally intended for Hasidic Jews, but due to lack of financing, only 30 of the planned 60 houses were constructed. The remainder of the land was apportioned to several other groups: Syrian, Iraqi, and Persian Jews. In the 1890s another neighborhood, Eshel Avraham, was erected next to Kirya Ne'emana for Georgian and Caucasian Jews. These neighborhoods were virtually abandoned during the 1929 Palestine riots and the homes taken over by Christians and Muslims. The remaining Jewish residents left with the Arab takeover of East Jerusalem after 1948.
