A synagogue called Chasidim Schul was the first Hasidic prayer house in Lviv, which was not subject to the local qahal. It was built in 1791 on a plot owned by the suburban Jewish community (conscription number 29½), at the corner of Łazienna and Bożnicza streets (DALO). Across the street, closer to the Poltva river (Łazienna street 1 – Bożnicza street 2), the suburban ritual bathhouse, the mikvah, was located. Originally this synagogue was made of wood; it was still wooden in the mid-19^th century as marked on the 1849 cadastral plan of Lviv. The stone synagogue Chasidim Schul was constructed in the second half of the 19^th century, and so it is recorded in the 1890 cadaster.

During its existence, the stone synagogue Chasidim Schul underwent several thorough renovations, so it is unknown how it looked originally. In 1883 the synagogue’s galleries and vaults were reconstructed under a project designed by Kalikst Krzyżanowski. The old vaults were demolished, and new ones were raised higher. In the early 20^th century the synagogue was reconstructed under a project designed by architects Artur Schleyen and Maurycy Silberstein who was involved in the reconstruction of the attic. The synagogue was given a historicizing stylistic design at that time.

The synagogue suffered damage during the November 1918 pogrom, when the whole Jewish quarter on Bożnicza street was on fire. It was then that the interior was burned and the façades were damaged. The destroyed building was rebuilt under a project designed by Henryk Orlean in 1919. In 1941 it was blown up by the Nazis. Now there are some utility buildings and a café in this place fenced off with a high wall. The only surviving photograph of the synagogue Chasidim Schul was taken after the 1918 pogrom.
