In the 1980s, Rabbi Yissachar Dov spearheaded plans for a huge synagogue to be erected in the Kiryat Belz neighborhood of Jerusalem. The building, which would have four entrances accessible to each of the four streets of the hilly neighborhood, would be an enlarged replica of the structure that the first Rebbe of Belz, the Sar Shalom, had built in the town of Belz. It would include a grandiose main synagogue, smaller study halls, wedding and Bar Mitzvah halls, libraries, and other communal facilities.
