In the Wertheim-parc in Amsterdam you can find this Auschwitz Monument, designed by Jan Wolkers. The monument consists of broken mirrors reflecting the sky and symbolizes that after Auschwitz the sky never is undamaged anymore. The text in the background says "Never Auschwitz anymore".
It is realized in commission of the "Dutch Auschwitz Committee" who organizes a remembrance once a year at the monument.
