After the World War II, the building was used for secular purposes because the Smíchov Jewish community ceased to exist in the Shoah.

The Jewish Community, indebted since the original building project and totally unprepared for another expense, gained financial means to replace the ruin with a new synagogue from Franz Ringhoffer II, Smíchov mayor, businessman (founder of the important Smíchov railway car factory) and surprisingly enough, a gentile.

In 1897, the central government of the Austrian-Hungarian Empire failed to enforce a law that would guarantee equal rights to Czech- and German-speaking people.

[2] Since the 1920s the Smíchov Jewish Community had looked for a site to build a new synagogue but because they did not succeed, they decided to rebuild the existing one.

After the World War II, the Smíchov Jewish Community was not re-established and the building passed to hands of a near factory Tatra, which used it as a warehouse.

Some structural interventions were made (new concrete floor, change of storey disposition and construction of elevator), they caused damage to the synagogue and in 1986 it was proposed that it be demolished.
