I saw this too. It’s sad that no one is sure what to do with it. To prevent the inevitable souvenir hunting, I think one of the governments needs to either open it up, catalogue it and rebury the bodies, or seal it up for good. I think there’s a precedent at Fort Douaumont where, if I recall correctly, there are many German bodies (killed in a huge accidental explosion) were simply sealed in and left for good.
