Duke Albrecht V, the persecution of the Jews in the autumn of 1420 grew to a bloody climax in 1421. In the beginning were many imprisonments, with starvations and tortures leading to executions. Children were deprived and deceived into eating unclean foods, those that were defiant were "sold into slavery" or baptized against their will. The poor Jews were driven out, while the wealthy were imprisoned. The few Jews still living in freedom took refuge in the Or-Sarua Synagoge at Judenplatz, in what would become a three-day siege, through hunger and thirst, leading to a collective suicide, A contemporary chronicle exists, entitled the "Wiener Geserah", translated from German and Hebrew as the "Viennese Decree". It reported that the Rabbi Jonah set the Synagogue on fire for the Jews at Or-Sarua to die as martyrs. This was a form of Kiddush Hashem in order to escape religious persecution and compulsory baptism.

It consists of a 10 by 7 metre block that is 3.8 metres tall. It is located in the northwestern end of the square before the Misrachi-Haus and faces the Lessing Monument in the southeast, with its walls parallel to the length of the square. The memorial is site-specific in many ways and is therefore dependent on the setting of Judenplatz. One facet of this site-specificity is that it was designed at a domestic scale. It was imagined as if one of the surrounding buildings had a room cast inside out and
