A couple of years ago I visited Nordhausen
https://www.buchenwald.de/en/29/
I was surprised to find that the majority of the visitors were school children from Germany on School trips. One of the teachers was telling me it was part of the school syllabus and they had to learn about the Nazis ( there way of separating them selves from the horror I presume)
If you are ever in that part of Germany I would recommend it as the tunnels are truly amazing in there size. They had a scale model of the whole complex that was about 3 feet long, we walked for about 30 mins and that was less than 4 inches on the model.
Maybe our schools should have it on there syllabus? In my view its probably more interest than wives of Henry 8th or Oliver Cromwell.
