My wife and I visited Paris in July (normally an insane idea due to tourist crowds, but there were few crowds this year) the worksite at Notre Dame is very impressive, they have covered the security fence with a systematic explanation of the restoration and repair process.
Over the past year, the crew has painstakingly reinforced the structure so that they don’t further damage the building as they remove the non-repairable portions. Now they are slowly removing the those portions and beginning the repairs.
It is a very impressive process, it is clear that the French consider this a national priority.
If the news stories covering the aftermath remain correct, significant donations were pledge from many sources PREDICATED on a historical rebuild like we are seeing here. The LEFT in France, very strong, were the ones putting forward 'alternative uses' and they remain muttering in their beards!
