I mean sure, it will likely be "as good as new" in the end, superficially speaking.
Still, it went through centuries pretty much unscathed, including two word wars that saw the complete destruction of entire towns. The worst damage it ever suffered was during the Revolution, and that was mostly pillaging and status being defaced (or I should say, beheaded) as they mistook them for depicting kings, lolz. It never really saw any major changes or refurbishing either.
So it's pretty sad that the worst to ever happen to it was an unfortunate accident - while it was being renovated, no less.
