The Jewish inhabitants of Singen initially belonged to the synagogue community of Constance. In the course of the 1920s, their number increased to such an extent that a congregation foundation and the construction of a synagogue were seriously considered. In order not to always have to travel the long distances to the synagogues in Gailingen and Constance, they first set up a prayer hall. Salo Schärf, owner of the furniture store "Roll and Co.", made the rooms above his store in the Poststraße 19 and 21 (today's Freiheitstrasse) available for this purpose.
