The reaction to the fire on Facebook is, for the most part, over-the-top and ridiculous - with several idiots blaming Islamic terrorists without a shred of proof - in fact, everything up to this point points to it having begun due to the construction that's being done and if you look at where the fire began you will see that is exactly the area. They've apparently saved the artwork and artifacts and as of twelve minutes ago the Guardian reported (whether it's accurate I know not): Notre-Dame’s main structure has been “saved and preserved”, a Paris fire official has announced.
“We can consider that the two towers of the north belfry Notre-Dame have been saved,” he tells BFMTV. “The structure of Our Lady is saved as a whole.”
