The Parisien newspaper has reported that investigators are considering whether the fire could be linked to a computer glitch or related to temporary elevators used in the renovation that was underway at the time the cathedral caught fire.
PARIS (AP) — A "computer glitch" may have been behind the fast-spreading fire that ravaged Notre Dame, the cathedral's rector said Apirl 19, as architects and construction workers tried to figure out how to stabilize the damaged structure and protect it from the elements.
The fire burned through the lattice of enormous oak beams supporting the monument's vaulted stone ceiling, dangerously weakening the building. The surrounding neighborhood has been blocked off, and stones have continued to tumble off the sides of the cathedral since April 15th's devastating blaze.
Speaking during a meeting of local business owners, rector Patrick Chauvet did not elaborate on the exact nature of the glitch, adding that "we may find out what happened in two or three months."
On April 18, Paris police investigators said they think an electrical short-circuit most likely caused the fire.
The Parisien newspaper has reported that investigators are considering whether the fire could be linked to a computer glitch or related to temporary elevators used in the renovation that was underway at the time the cathedral caught fire. Chauvet said there were fire alarms throughout the building, which he described as "well protected."
Charlotte Hubert, president of a group of French architects who specialize in historic monuments, told BFM television that experts plan to spread a custom-made peaked tarpaulin across the cathedral's roof, with enough space to also shield workers rebuilding the frame.
French President Emmanuel Macron is expected to set out reconstruction ideas during meetings April 19 with officials from the United Nations' cultural agency, UNESCO.
Macron is moving quickly on the fire-ravaged monument's reconstruction, which is being viewed both as a push to make it part of his legacy and a way to move past the divisive yellow vest protests over economic issues in France.
Notre Dame's reconstruction is prompting widespread debate across France, with differing views emerging over whether it should involve new technologies and designs. Macron's office has, for example, said the president wants a "contemporary architectural gesture to be considered" for the collapsed spire, which wasn't part of the original cathedral.
Macron hasn't offered any specifics on his vision for the roof or whether the frame should be wood, metal or concrete, according to his cultural heritage envoy, Stephane Bern. He has named a general, Jean-Louis Georgelin, former chief of staff of the armed forces, to lead the reconstruction effort.
Over $1 billion has already poured in from people from all walks of life around the world to restore Notre Dame.
Judith Kagan, a conservation official at France's Culture Ministry, said the artworks inside Notre Dame had suffered no major damage from the fire and the pieces were being removed from the building for their protection.
The Notre Dame fire delayed Macron's long-awaited plans to quell anti-government protests that have marred his presidency. The French leader abandoned a planned TV address to the nation on the evening of the fire, heading to the scene instead and declaring: "We will rebuild Notre Dame."
According to an opinion poll by BVA institute published April 19 — the first carried out since the fire — Macron has gained three points in popularity in the past month with an approval rating of 32 percent. That advance puts him back at the support level of September, before the yellow vest crisis, BVA said.
Although all French polls show that Macron's popularity has remain depressed since a tax increase on retirees last year, they suggest his party may be ahead in France's May 26 European Parliament election, with Marine Le Pen's far-right party, the National Rally, close behind.
Macron is now expected to detail his new measures next week. Macron earlier was planning to respond to demonstrators' concerns over their loss of purchasing power with tax cuts for lower-income households and measures to boost pensions and help single parents.
Despite the destruction of Notre Dame dominating the news in France, a new round of yellow vest protests is planned on April 20 across the country, including in Paris.
In a hopeful development April 19, 180,000 bees being kept in in hives on Notre Dame's lead roofing were discovered alive.
"I am so relieved. I saw satellite photos that showed the three hives didn't burn. I thought they had gone with the cathedral," Nicolas Geant, the monument's beekeeper, told the AP.
Geant has looked after the bees since 2013, when they were installed as part of a city-wide initiative to boost declining bee numbers.
Since the insects have no lungs, Geant said the CO2 in the fire's heavy smoke put the bees into a sedated state instead of killing them. He said when bees sense fire they "gorge themselves on honey" and protect their queen. He said European bees never abandon their hives.
