The Catholic Church needs to step up to the plate pay & oversee the rebuilding of Notre Dame or some god-awful modern architectural, anti-Christian, anti-European (as well as anti-France) monstrosity will take its place. Norte Dame needs to be reconstructed as near as possible back to what it was. Nothing else is Norte Dame, every Frenchmen & Frenchwomen should know that! If France means anything to them this is what they will demand!
Technically speaking, the Church does not own the building.
Sadly, given the Church’s recent track record of architectural abominations such as the Taj Mahony in L.A., we can’t assume that they’d come up with something better than the secular authorities.
I'd imagine the RCC will have input on the rebuild...but so will France.
Too many islamists.
