Hundreds of thousands of Roma people, or Gypsy, were persecuted and killed by the Nazis during World War II.
But half a century on, the German city where the killings of the Roma people was planned has now become the place where they are offered the hope of a better life.
One German group in particular is determined to help the Roma, said to be among the most persecuted people in Europe, according to rights group Amnesty International.
