The Jonas department store was built in 1907 by Alfons Jonas' father in Kiel - Gaarden. After the First World War, his son Alfons took over the business. Shortly after the National Socialists seized power in 1933, there was a call for a boycott of all Jewish businesses on April 1, 1933, which of course also affected the Jonas department store. In 1934, Alfons Jonas decided to emigrate. The family emigrated to Palestine via Switzerland. There, Alfons Jonas built up a new life for himself and his family in Haifa by founding a household goods business.

The cemetery from 1717 on the Schwälkenberg in the north of Schwerin's old town, in the Werdervorstadt on the street 'Am Heidensee, has been cut through by Bornhövedstraße since the early 1950s. At that time, only a third of the southern part with its funeral hall was occupied.

Cemetery for forced laborers, prisoners of war and concentration camp prisoners of the Reichswerke ‚Hermann Göring‘ who perished under inhumane working and living conditions.

The construction of a central ‚Ausländerfriedhof‘ began in the early summer of 1943. The Reichswerke „Hermann-Göring“ made the land with the old field name 'Jammertal' available for this purpose. The area was a small hill in the otherwise flat landscape, as the unusable earth accumulated during the construction work of the Reichswerke ‚Hermann Göring‘ had been dumped there.

Due to the increased number of members of the Jewish community in Braunschweig, which meant that the synagogue room in the community center used until then was no longer sufficient, it was decided to build a new synagogue in the inner courtyard of the community center in Steinstraße, directly adjacent to it and to the bunker. In January 2006, Jürgen Justus Becker conceived and realized the campaign „1938 Bausteine für die Synagoge“ on a voluntary basis, whereby the number  1938 is intended to commemorate the November pogroms of 1938 and their consequences.

The Jüdische Gemeinde Hildesheim e.V. was founded on January 25, 1997. It is a member of the Landesverband der Jüdischen Gemeinden von Niedersachsen K.d.ö.R.

On 10 November 2009, the liberal community was able to inaugurate its synagogue with a community center.
