In all, 56 survivors gathered under a huge tent on Monday set up over a gate and railway tracks at the site of the former camp.

Auschwitz survivors warned Monday of the rising antisemitism and hatred they are witnessing in the modern world as they gathered with world leaders and European royalty.

At Auschwitz, the Germans left behind barracks and watchtowers, the remains of gas chambers and the hair and personal belongings of people killed there. The “Arbeit macht frei” (work will set you free) gate is recognized the world over.
