@Setanta,
Looking at your photo, I would guess the video was taken before, as there's a hell of a lot of devastation in the pic.
I've just sat and watched it through again, and couldn't see a sign of any damage, and I'm sure they wouldn't have been able to clear and rebuild all in the same year.
I remember walking around areas like that in London, and that was in the early sixties, getting on twenty years after the war.
Granted, the country was all but bankrupt, but still, twenty years is a long old time, even for British builders.
