was in the center of the quarter, located at the corner of 5th and Gaskill Streets. It was here that actors of the Yiddish theatre performed, Jacob Adler and Boris Thomashevsky. In the 1890s, the S. 4th Street vegetable and meat market was started on the sidewalks; it eventually grew into the fabled S. 4th Street pushcart market, still remembered till this day. Markets were located along S. 2nd Street, the Washington Market along Bainbridge Street from 3rd to 5th Streets and in the 4th Street pushcart market. Sweatshops in the quarter numbered over one hundred. On the 300 block of Lombard Street alone there were five sweatshops. After 1900, Jews moved south across Washington Avenue and within just a few years they lived in great numbers south of Washington Avenue and east of Broad Street. Many Jews in the clothing trade prospered during the 1920s and moved to West Philadelphia and Strawberry Mansion. After Congress cut off immigration from Eastern Europe in 1924, the old Jewish quarter began to die out. Although its demise was slowed, first by the Depression and then by the effects of World War II, outward movement from the quarter accelerated after the war ended. Today, there are four synagogues operating in the original Jewish quarter. Two buildings originally built as synagogues—Congregation B'nai Abraham, 527 Lombard Street (built in 1910 and still continuing to operate and maintain a congregation), and nearby B’nai Rueben, 6th & Kater Streets (built in 1905 but used for commercial purposes since 1956, and converted residential in 2014) —survive. Historic Congregation B'Nai Abraham is located in the Society Hill section of Center City Philadelphia, and is supported by a lay led leadership board who act as stewards of the historic building. The congregation was established in 1874 as the "Russian Shul" following a wave of immigration to the Jewish Quarter of Philadelphia at the time, fleeing from Czar Alexander II. It moved into present space around the 1910s, making it historically significant as the oldest building in Philadelphia that was originally constructed as a synagogue and has been in continuous use as such. With the departure of much of the neighborhood's Jewish population in the mid-twentieth century, the congregation was no longer able to support a full-time rabbi and frequently lacked a minyan for Shabbat services. In the early 21st century, it became affiliated with the Chabad movement and is now
