The International Holocaust Remembrance Day is the first universal commemoration in memory of the victims of the Holocaust. January 27 is the date, in 1945, when the largest Nazi death camp in Auschwitz-Birkenau (Poland) was liberated by Soviets troops (Wikipedia).
Every year, on the 22nd January, this train wagon appears in Piazza Bra. It is quite impressive, rusty red and battered and it bears a dreadful chalk writing saying "54 stucke", the german for "54 pieces". This nightmare wagon was used from 1943 to 1945. It makes me shiver to think that innocent people were treated like "pieces" and shut in this iron box for a long, terrifying journey to Auschwitz-Birkenau.
