Yeah, it’s bad, to say the least.
Notre Dame Cathedral will never be the same, but it can be rebuiltThe trees that made up the roof's wooden structure were cut down around 1160, and some sources estimate that the beams accounted for 13,000 trees, or about 21 hectares of Medieval forest, many of which had been growing since the 800s or 900s. "You have a stage in France where deforestation was a problem; these buildings consumed huge amounts of wood." That's according to Columbia University art historian Stephen Murray, who spoke with Ars Technica. All that wood, he said, supported an outer roof of lead—until the wood burned and the roof collapsed.
I'm more surprised that the owner allowed it to happen.
How so?
Like Mick said, “superb achievement built by men 800 years ago”. Love looking at old architecture and just envision the work being done.
