Former Adath Jeshurun of Jassy Synagogue, Romanian Jewish synagogue in Lower East Side, Manhattan, United States.

The Former Adath Jeshurun of Jassy Synagogue at 58-60 Rivington Street is a Moorish Revival structure completed in 1904 and designed by architect Emery Roth. The building displays ornamental stonework, arched windows, and decorative elements typical of that architectural style, with its interior once featuring a vaulted ceiling and balconies for the congregation.

The First Romanian-American Congregation, founded in 1881, worshipped at 70 Hester Street and moved to 131 Hester Street in 1886. In 1903 it bought a tenement at 58-60 Rivington Street and had Emery Roth design a synagogue; the cornerstone was laid on November 22, 1903, and the building opened in early September 1904 before a crowd of over 10,000. Financial trouble led to a mortgage, and by late 1908 the First Warsaw Congregation had acquired the building, renamed Erste Warshawer Synagogue; a legal dispute lasted until 1910.

Services were held in Hebrew and Yiddish, and the congregation drew George and Ira Gershwin, Senator Jacob Javits, Samuel Goldwyn and George Burns. After the Warsaw Ghetto uprising, hundreds of Polish immigrants gathered here, including 2,000 for a 1935 tribute to Józef Piłsudski.

The building now houses artist studios and residential units, so visitors can only appreciate its exterior architecture from the street. The location on Lower East Side is easy to access and gives you the chance to explore nearby buildings and the neighborhood's character as you visit.

When the building first opened, it attracted a crowd so large that it became an instant symbol of the community's arrival and success. Today fewer people stop to notice this structure compared to other Lower East Side landmarks, yet its ornate facade still displays the ambition of that era.
