At the entrance to the cemetary in Büderich, just to the right as you go in, there is a memorial sculpture by Peter Rübsam, erected in 1988, consisting of seven basalt pillars, each with a bronze plaque in front of it. On each plaque is written one word: Dachau, Buchenwald, Theresienstadt, Riga-Kaiserswald, Treblinka, Maidanek, Auschwitz
