Notre Dame Is Burning

[classicdrogn]

The structure is currently considered "unstable",

That much is no surprise - for architecture and engineering, anything is considered hazardous until proven stable, not the other way around. For a cultural and historical location with the kind of tourist traffic Notre Dame sees, I'd expect weeks of safety inspections even if there hadn't been any significant damage, let alone having tons of burning roof and support beams collapsing onto the stone ceiling vaults.
