I have been chasing this all down.
There is more to this building than is common.
The ‘ceiling’ of the church is stone, with a roof of wood.
The wood burned above and only fell inside at one, albeit large hole.
It is an expensive mess, and some stuff was destroyed...but the really cool stuff is just fine.
I could be wrong, there are many conflicting reports.
Read today 13,000 oak trees were cut to build this church.
I got to see it in 89...when I did not appreciate such things.
This evening it was reported that 3 out of 4 of the beautiful stained glass windows have been destroyed. However, they must have detailed pictures/patterns of these windows and should be able to reproduce them.
It takes centuries to grow such trees.
I don't think we could even make such a thing anymore. We are not at that level of multi-generation-spanning Faith. It does not just require money, technology, resources. It requires a civilization.
It's not just that we don't know how. Far more fundamentally, we don't know WHY.
