Jean-Louis Georgelin told a French parliament commission Wednesday that workers are still securing the structure. Concerns persist that Notre Dame’s vaulted ceilings could collapse.
“Even if we are rather confident and even if all the indicators seem positive, it is still too early to affirm that the cathedral is saved,” he said.
At Davos, Trump devoted almost the entirety of his 40 minutes on stage listing what he said were his economic achievements at home. But in one small gesture to Europe, Trump invoked the continent’s rich history and its development of wealthy commercial centers before launching into a long-winded tangent about last year’s fire at the Notre Dame cathedral in Paris. Trump used it as an example of how Europe once had “unbridled ambitions,” and said that the church would one day be “restored magnificently” to once again be “giving glory to god.”
Trump made no mention of buying Notre Dame and turning it into a hotel.
Alexa Dufraisse, a dendroanthropologist, suggested that studying this nearly 1,000-year-old wood of the now-gutted attic of Notre Dame could give us insight into historical weather patterns, which could in turn teach us about modern climate change. She told Science News that this study could not have been undertaken had the fire not occurred.
Okay well the link is just to a blog post about Notre Dame but the author, Kevin Drum, doesn’t think the spire should be reconstructed, and describes the old spire as ‘ugly’ amongst some other words.
A bell of Notre Dame, when they were in the place before the fire
Science News reports that archaeologists are among the more than 200 researchers in the Association of Scientists in Service of the Restoration of Notre Dame of Paris, France’s National Center of Scientific Research (CNRS), and the French Ministry of Culture who will examine the twelfth-century cathedral damaged by fire.
There’s little documentation of the building process of Notre Dame, which began in 1163 and continued for about 200 years. Olivier de Châlus has devoted himself to teasing out the unwritten rules of construction — how builders decided the size of columns or the height of flying buttresses, for example. He notes that builders lifted 100-kilogram stones more than 60 meters off the ground without the benefits of modern technology. Exactly how this was accomplished has been lost to time, he says.
As architects, builders and historians begin the process of rebuilding Notre Dame, Brian Katz, an acoustics researcher at CNRS, the Centre National de la Recherche Scientifique, and Sorbonne University in Paris, is on a mission to help restore the building’s sonic signature.
Temporary roof cover on Notre Dame
Eric Wirth, vice president of the Guild of French Architects, declared that it would be a grave mistake to rebuild the roof in anything but same wood used in its original construction. He noted its natural fire resistance. “Notre Dame has been there for 800 years. If the structure had been made of steel, there would be no cathedral to speak of today,” he said. In a fire, “iron holds for half an hour, an hour, and then writhes, pulls on the walls and collapses everything.”
Scientists with the French national research organization CNRS are embarking on a multimillion-euro effort to study the 850-year-old building and its materials with the goal of illuminating how it was constructed.
The simple answer is that we don’t know yet.
The news comes two months after the Archbishop of Paris, Monsignor Michel Aupetit, announced that a final evaluation of the damage would be concluded in Spring 2020. “We will have to encircle the scaffolding, then put a second scaffolding over it,” he said. “From this new scaffolding, workers will descend by rope and cut it bit by bit into small pieces and this will take a long time.”
