During my last business trip in Poland at Katowice I had the chance to visit the Auschwitz-Birkenau Memorial and Museum (about 30-40 min driving distance from Katowice). It has been a shocking experience, I do not have nothing to add to the title of this post that is one of the quotes I read in the Museum and was said by the spanish philosopher Jorge Santayana.
Here below a few shots taken during my visit. Any comment is really superfluous.
