I'm a volunteer guide at IWM. Just to add, "Culture under Attack" is a temporary exhibition that ends on 5th January - so be quick off the mark if you want to see it.
Was going to say - an indefinite article makes a hell of a difference here. For those unaware, it's called 'Culture Under Attack', no 'A', permission to get excited denied
I love the IWM. Dad and Nan took me there as a kid and have been back twice with my eldest daughter.
Was totally gobsmacked at the Holocaust exhibit a few years ago, not sure if its still there but well worth a look.
Truly moving when I saw it several years ago. Remember the IMW being packed with school trips with loads of kids arsing around. The silence from those kids when they went through the Holocaust exhibit and the look on their faces at the end shows why we should never, ever forget the depths to which the human race can sink, never forget those who fought against it and never allow it to happen again.
A good exhibition “A Culture under Attack” is worth seeing and the revamped museum.

How having survived the Blitz the white working class have all but disappeared from the East End of London?
The second world war exhibition is absolutely exceptional, and to be fair to the other exhibitions, the only reason I went.
