A very dark page of mankind history can be experienced 2km outside city of Oświęcim, 65km from Krakow. Even if it is a spot where millions of tourists come every year, don't think it is easy to visit the concentration camps of Auschwitz and Birkenau. The spirits of the dozen of innocents murdered there seem to tear you apart during your walks on the alleys and it feels like every brick of the blocks is crying. Pain, death and humiliation, learning about all those atrocities you will overwhelm you. But it is a lesson we must learn.
