Anshe Chesed and Rodeph Sholom are respectively the oldest and second oldest surviving synagogue buildings in the city, and some of the oldest in the country. Both were constructed for German Jewish congregations in German architectural styles: Gothic Revival and Rundbogenstil (“round-arch style”), and feature red brick, central staircases and symmetrical façades with recessed central sections and square towers. Kehila Kedosha Janina Synagogue is the only Greek Synagogue in New York and the only synagogue of Romaniote Jews in the Western Hemisphere. The Eldridge Street Synagogue was America’s first major house of worship built by Eastern European Orthodox Jews. The yellow brick building features Moorish and Romanesque details and rich ornament. At its peak in the early 20th century, the synagogue hosted as many as 1,000 worshippers at services, but was forced to close in the mid-20th century when the area’s Jewish population began to dwindle. In 1986, the Eldridge Street Project funded a large-scale restoration of the building, which was repurposed as a museum. The Former Congregation Anshe Chesed, Kehila Kedosha Janina Synagogue and the Former Eldridge Street Synagogue are all designated New York City Individual Landmarks.

The Lower East Side, traditionally an immigrant, working-class neighborhood with a rich Jewish history, has in recent years experienced rapid gentrification. Despite A LOT of changes, many of the neighborhood's diverse local landmarks have survived into the 21st century.

A Gothic Revival synagogue at 172 Norfolk Street. Built in 1849 for Congregation Ansche Chesed, it was sold to Congregation Shaari Rachmim in 1873, to The First Hungarian Congregation Ohab Zedek in 1886, and to congregation Sheveth Achim Anshe Slonim in 1921, before its abandonment in 1974 and subsequent vandalization. In 1986, Jewish Spanish sculptor and painter Angel Orensanz purchased the property, restoring it and converting it to an art gallery and performance space. It was designated a New York City landmark in 1987.

New York City’s oldest extant building originally built as a synagogue is this Gothic Revival structure designed by architect Alexander Saeltzer. The synagogue was built in 1849 by Reformed Jewish Congregation Ansche Chesed (People of Kindness) which was made up primarily of German Jews, as well as Dutch Jews and Polish Jews. (This group generally emigrated to New York City a few decades earlier than the wave of Eastern European Jews who later populated the Lower East Side so densely.) It was the largest synagogue in the United States at the time and could hold up to 1,500 worshipers. Services were conducted primarily in German. Services were accompanied by musical instruments, including an organ that was added in 1869 at the same time as family pews were introduced, with men and women sitting together - evidence that the congregation was modernizing and Americanizing. In 1873, the congregation merged with another and the building was sold to Orthodox Congregation Shaari Rachmim. Shari Rachmim removed the organ and remained in the building until 1886. Then, First Hungarian Congregation Ohab Zedek occupied the building until 1921 and Congregation Anshe Slonim worshipped there from 1921 to 1974. Like so many others, the 1970s brought abandonment and decay to the historic building until it was rescued by artist Angel Orensanz in 1986. It was designated a historic landmark in 1987 and is now used as a well-known and beloved event space.

Upon reaching New York, many Jewish immigrants settled on the Lower East Side, establishing new congregations and social aid societies specific to local communities of the old country. Small synagogues were so common that a stretch of East Broadway was known as “shtiebel row,” after the Yiddish term for a small space for prayer (in contrast to larger synagogues). Over time, Manhattan’s Jewish population shifted to other parts of the city, causing Lower East Side congregations to dwindle. Many synagogues were sold, shuttered, or abandoned, and some have since been demolished. Still, the neighborhood bears many traces of its once-vibrant Jewish life.
