Sorry for not having the exact date available but it appears like the only certainty is that it will be on display during the Spring of 2010. No start or end date has been set. If you are planning a vacation try to keep in mind the vatican said Spring, so my money would be it closing down before June.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
