I suspect the west end towers will be okay and the west end portal.
Not sure how badly damaged the skin of the rest of the cathedral will be.
The big fire was the roof. I can't see the vault surviving. Too much heat.
It isn't clear what happened below. What was there to burn on the ground? Seats? An organ?
I wonder what has happened to the windows.
They can replace the roof and the spire easily enough if the walls and flying buttresses are okay.
