Yes, the roof and the spire are gone, and some priceless treasures are lost, but many others were saved. Already stories of heroism are emerging: the chaplain who braved the blaze, the human chain that rescued precious artwork. Donations and pledges are pouring in. Notre Dame will be rebuilt, though it will doubtless be on "cathedral time," not at the pace we might expect in the 21st century.
Even more encouraging were the perspectives the articles contained: that cathedrals are patchwork creations. The fallen spire we lament was a relatively late addition to Notre Dame. Europe is filled with cathedrals that have risen from fires and firebombing: St. Paul's in London, the cathedral in Dresden. Besides, in many ways the places are as sacred as the buildings, and they remain sacred even when the stones are singed and the rafters give way.
The most optimistic accounts mentioned the survival of the gold cross on the altar and the votive lights that remained lit throughout the ordeal — also the fact that the fire happened during Holy Week, the most sacred time in the Catholic church's liturgical year, a time when we celebrate redemption and resurrection.
I'll end with this from the Washington Post's architecture critic Philip Kennicott:
Meanwhile, the roof will rise again, and in a century some bored teenagers will stand in the plaza before the great Gothic doors and listen as their teacher recounts the great fire of 2019, just one chapter among all the others, and seemingly inconsequential given the beauty of the building as it stands glowing in a rare burst of sunlight on a spring day in Paris.
