QUOTE: "If the fire really was an accident, it is almost impossible to explain how it started. Benjamin Mouton, Notre Dame's former chief architect, explained that the rules were exceptionally strict and that no electric cable or appliance, and no source of heat, could be placed in the attic. He added that an extremely sophisticated alarm system was in place. The company that installed the scaffolding did not use any welding and specialized in this type of work. The fire broke out more than an hour after the workers' departure and none of them was present. It spread so quickly that the firefighters who rushed to the spot as soon as they could get there were shocked. Remi Fromont, the chief architect of the French Historical Monuments said: "The fire could not start from any element present where it started. A real calorific load is necessary to launch such a disaster"." source: https://www.zerohedge.com/news/2019-04-24/burning-notre-dame-and-destruction-christian-europe
