I've visited it 3 times.

While I do agree most religions perform social functions quite well that secular organisations struggle with, I'm not overly impressed, frankly, by the way various faiths squandered significant money drawn from their parishioners on monuments, religious icons, gilded decorations and on themselves, rather than applying rather more of it to the benefit of their parishioners.

There are more than enough gothic piles remaining - including several of rather more architectural significance than Notre Dame.

As I said, consider what could be, not what was. Forget about trying to recreate the past - if you really want to do that, eschew all that is modern - starting with the clothes on your back, electronics, cars, and return to living like nomads with little more than animals, skins and wooden tools.
