This is absolutely terrible, but it looks like it won't be as catastrophic as originally predicted. They seemed to be indicating they thought the whole structure would be lost just two hours ago. Losing the spires and the stain-glassed windows is a huge blow, though. Very sad, but thankfully the structure as a whole has survived.
I wonder if wouldn't it be better, due to impossibility of reconstructing the interior without it reeking artificiality, to turn the renovated cathedral into some sort of museum. Just a thought.
Why would it seem artificial? So many churches have burned down over the centuries and have been rebuilt perfectly and beautifully. Turning it into a museum means accepting to close the chapter on this church and, by extension, on Paris' and France's Christian identity. Which would seem completely unacceptable to me. In that case, it would not just be a metaphor for European civilization burning (fully expecting this to be deleted again) - it would literally be that.
