"t's pretty clear the stained glass windows are gone, there's smoke and scorch marks on the outside of the structure."
"Evoking a "little piece of collapsed vault", André Finot returned to the damage he saw in person. "The stained glass had not been touched, the three beautiful rosettes of Notre Dame, which date from the twelfth and thirteenth centuries have not moved. These are stained glass windows of the nineteenth century, much less important in our imagination that may have been affected, but not the jewels of the thirteenth century. It's a bit of a miracle. "
Looking at pictures of the aftermath of the fire with my mother and sister, it’s equally miraculous that the altar was virtually unscathed (not even the candles were melted). They’re not particularly religious, but they were given the impression that divine intervention was involved as far as the altar was concerned.
I will say it is heartbreaking what happened. If I ever had the opportunity to go to France, visiting the cathedral would have been my main desire (with the lesser desire to visit places connected to the Joan of Arc story).
