I would not have expected it to be very flammable - perhaps just the roof?

What a pity. I've walked past that cathedral many times (and also been inside). It is located right in the heart of Paris.

Much of the interior of the cathedral, particularly the bell tower, is full of wood. A lot of it intricate carved and centuries old.

I'm hearbroken watching the news. I've been to Notre Dame a couple of times and it's a beautiful building. All the artwork, carvings, the relics, the tower will all be gone. I hope they're able to limit the fire and save the stain glass, but there have been people on the news just now estimating that there might not be anything more than the stone towers left by the time it is out.

Terrible news.

Lead was used extensively in constructing cathedrals due in part to its low melting point.

According to the Paris Fire Brigade, Brigade de sapeurs-pompiers de Paris, an ongoing renovation project, involving many tons of lead, may have contributed to the incendiation.

All that scaffolding around the apparent heart of the fire, along with the report of ongoing lead-working, much of which, presumably, involves direct flame application, to me strongly suggests that some activity associated with the renovation project may have incipiated the catastrophe.

I passed it countless times when I lived in Paris. Seeing it burn is unbearable. :cry:

La cathédrale de Notre-Dame ne s'effondrera pas à cause de cette calamité; ses volant-arcs-boutants la soutiendront pour tous nos jours.

The Cathedral of Notre Dame will not collapse due to this calamity; its flying-arch-buttresses will support it for all our days.
 
I hope the hunchback made it out OK.

Cheers

Yeah, I guess I had forgotten how much woodwork was in the interior/base. But at the same time, my understanding is that the roof is not structural and it looks to me like the ceiling is entirely masonary. So I wonder if it is possible for the roof to burn and fall off without touching the interior?.....though the spire collapsing into it doesn't help, and if it did collapse the ceiling arches it could be structurally catastrophic.

Support?
The vault was in lateral compression - what is left of the vault still is. The flying arches resist the outwards pressure of the vaults - meaning they meet it with corresponding inwards force.
Had more of the main vault collapsed, would the lateral pressure of the flying buttresses have pushed the side walls over inwards?
