We did Oradour (sur Glane) with the kids when they were about 11 and 13.
They were very quiet.
It is a startling memorial (though I think it’s been refreshed several times) that needs to be kept to remind future generations.
The visitor centre - well away from the village - is really well done.
If you get chance to stop off in Limoges on your way up, do. It was always a good place to visit and has its own ‘horrors’ particularly around the cathedral (which is stunning).
Used to spend a lot of time around Limoges when we had a place down there.
Having said that, probably about 20 years since we were last there
