Ben went on a school trip to Poland and visited Auschwitz.

Birkenau

Ben's comment.

Of course I knew about this, but I never understood the scale of it. I don't think I will ever fully understand the scale of it.

A colourful tribute to the memory of those who died in Auschwitz.

This floral tribute is at the foot of the killing wall.

One and a half million!
