a hub for immigrants during the early 20th century Chile

From the early 20th century, a significant number of immigrants arrived in Chile. Most left Central and Eastern Europe escaping pogroms and the East and the rising Nazi regime. In Santiago, the Jewish Benevolent Society Bicur Joilim was the address where they found lodging, food, health linguistic adaptation and guidance to find work soon. The Bicur Joilim also provided an Ashkenazi Orthodox, Ashkenazi Shul. Most new arrivals lived in modest conditions in nearby streets..

The name Bicur Joilim is - due to the “oi” in the spelling - the Yiddish version of the Hebrew (ביקור חולים - Bikur holim‎), mirroring the origin of most members. It was founded as an alliance of several Jewish institutions in the early twentieth century. It´s main purpose was not only the visiting the sick (direct translation of Bicur Joilim), a Mitzvah, but also benevolence, selflessness and loving-kindness.

In the 1930, Bicur Joilim moved to the premises in central Santiago, where it still resides (Avenida Matta). The present building was completed in 1943. After World War II Bicur Joilim went into decline and to virtually closing down. However, a dedicated group review it and Bicur Joilim remains strong. Today, Bicur Joilim is the only Jewish institution in the central Santiago central. Most Jews and their institutions moved to an affluent neighbourhood on the outskirts. The quarters around Avenida Matta are now home to new immigrants from around the world. The shul remains as a reference to the modest conditions of the Jewish immigrants and their origins in Europe, often from Stetls in the East.
