On this date we commemorate the victims of Porrajmos, the extermination of Roma and Sinti during World War II. The date was chosen to commemorate the night of 2nd August 1944 in which more than 4,000 people - men, women, children and elderly people - were murdered in the Zigeunerlager of the Auschwitz-Birkenau concentration camp.
In 2015, the European Parliament declared 2nd August European Day of Remembrance of the Nazi Extermination of Roma and Sinti to remember the 500,000 European Roma murdered in Nazi-occupied Europe.
In the following link you can see the commemoration ceremony held at the Zigeunerlager at which some of the young Tracer project participants were present.
