In 1977, the simple stone in the Amsterdam Ooster Cemetery was replaced by the Mirror Memorial. It consists of cracked mirrors that reflect the sky. According to the memorial's designer, the writer and sculptor Jan Wolkers, the cracked mirrors symbolise that "the sky will never be the same after Auschwitz". In 1993, the memorial was expanded and, together with the urn, it was moved to the Amsterdam Werthheim Park, the venue of the annual Auschwitz Memorial since then.
