The moslem population of France is hoping right now that this was in fact a fire caused by the renovation. Sad to see it burn, I took my wife and children there about two and a half years ago for Christmas. Hope it’s not damaged beyond repair, but these things happen. I just took a tour of Nürnburg and that place had churches and buildings just as old that were obliterated. As someone with an interest in history, it’s a shitty thing to see stuff like this happen.
