The Jewish communities of post-war Czechoslovakia understood the remembrance of the murdered and the commemoration of the horrors of war as a basic prerequisite for the beginning of a new life. Organized memorial services were one of the few moments when Jews and their families could, in a narrow circle of those who had gone through a similar hell, remember the dead as victims of genocide, different from other Czech victims of the Nazi occupation.
In public, it was forbidden to talk about the murdered as Jews, and similar to research into the fates of Holocaust victims, it was considered by state authorities to support Zionism.
That is why the unveiling of the memorial plaque in the Ústí nave in November 1953 was such a significant event. The plaque was supposed to commemorate the victims, but this was not allowed to happen in a public place. So it was placed directly in the prayer room, to the left of the tabernacle.
