Broder said that "the Jews don't need this memorial, and they are not prepared to declare a pig sty kosher." Completion and opening On 15 December 2004, the memorial was finished. It was dedicated on 10 May 2005, as part of the celebration of the 60th anniversary of V-E Day and opened to the public two days later.

Construction defects Three years after the official opening of the memorial, half of the blocks made from compacting concrete started to crack.

Some analyze the lack of individual names on the monument as an illustration of the unimaginable number of murdered Jews in the Holocaust.
