I was in Buchenwald a year ago, Its pretty much leveled. The wooden horse barracks that housed the inmates were gone, except for a couple that were “rebuilt” for the museum. The guard houses and the dog kennels are still there along with the solitary cells. The taller brick buildings (factories?) are still there in the far right corner of the layout. It was sad to see school buses of HS students arriving and watching the kids texting instead of paying attention to the guide. I thought the place was going to be huge, but it wasn’t as large as I thought. It is located on a tall hill surrounded by trees, and there are still some old train tracks there. I’m sure when the GIs entered it, it had a greater visual impact.

It is a matter of history that when Supreme Commander of the Allied Forces, General Dwight Eisenhower, found the victims of the death camps he ordered all possible photographs to be taken, and for the German people from surrounding villages to be ushered through the camps and even made to bury the dead.
He did this because he said in words to this effect:
“Get it all on record now - get the films - get the witnesses - because somewhere down the road of history some bastard will get up and say that this never happened.”
