The European Championship has been put into perspective for the England team after the squad visited Auschwitz and Oskar Schindler's factory in Krakow.
Football would have been the last thing on Roy Hodgson and his players' minds as they were given lessons in one of the darkest episodes in Europe's history.
After a light training session at their Hutnik base, the squad split into two groups.
One, led by Wayne Rooney, Hodgson, and Football Association chairman David Bernstein, headed to former Nazi death camp Auschwitz. The other, headed by captain Steven Gerrard, coach Gary Neville and FA director of football development Sir Trevor Brooking, visited the Schindler factory museum.
It was at Auschwitz that an estimated one million Jews, including a minimum of 232,000 children, lost their lives during the Second World War.
Schindler was a German who saved hundreds of Jews during the Holocaust by employing them at his enamelware and munitions factory.
Defender Joleon Lescott was one of 14 players to visit and said: "Days like today you tend to look back on as much as the tournament itself in years to come, the things you have done, the people you have met.
"I am sure, in years to come, the tournament will be a highlight but so will visiting places like this. It is fresh in my mind at the moment so it might take a while for it to sink in. I will go back to the hotel and think about what has been said to us by the guide."
The visits continued England's open-doors policy towards their Euro 2012 quest following a public training session at their base on the outskirts of Krakow . The absence of nine players from the main session, in addition to Jermain Defoe who has returned to England following the death of his father, spoiled it slightly for the 3,500 invited guests.
However, John Terry and Gerrard, who were amongst those who did pool and gym work, came out at the end to sign autographs. England plays its opening Group D game with France on Monday.
