The Azzurri visited the old concentration camp ahead of their debut at the Euro 2012, with many admitting that were touched by the tour around the site.
They also had the chance to listen to the stories of some survivors, with several players unable to control their emotions during the tour.
"This is something that leaves you shocked," Giorgio Chiellini said during a press conference. "It is hard to find words to describe what we felt.
"I studied these things at school, but seeing them in real life is very different. It was very touching to hear the stories of the survivors. The visit is something that we will remember forever."
Italy will kick off its Euro 2012 campaign against Spain on Sunday.
