“Bones from 130,000 unidentified soldiers in the ossuary at Verdun. Incredible.”
Ii remember going there as a child back around 1957. A friend of mine and I went around to the back side and there were little ground level windows. We looked in through many of them to be surprised at rooms full of human bones.
What’s more is that each ossuary at Verdun has a window allowing you to see the stacks of bones inside.
