Fire broke out at Notre Dame on Monday, and rapidly spread along the wooden roof frame, severely damaging the Gothic jewel. It is possible the fire was able to spread so quickly because of a “computer glitch” with the alarm system, rector Patrick Chauvet said on Friday.

Chauvet did not specify the nature of the glitch. The fire alarm went off at 6pm local time, but registered the blaze in the wrong place, the newspaper Le Parisien reported. Police investigators suspect an electrical short circuit was behind the fire.

“We may find out what happened in two or three months,” Chauvet said.

Archbishop of Paris Michel Aupetit told the newspaper Le Figaro that the “extraordinary generosity” from around the world following the fire will allow the Catholic Church to consider the cathedral’s “certain resurrection.”

The outpouring of support for repairing Notre Dame has also been exploited by grifters, however – the Patrimony Foundation (Fondation du Patrimoine) has warned of numerous scams seeking to siphon off donations, including a fraudulent website impersonating their own, but hosted at weebly.com.

Donors should avoid door-to-door solicitations, phone calls, mailers or internet campaigns, because they are most likely fraudulent, the FdP warned.

Meanwhile, French President Emmanuel Macron has vowed to rebuild the cathedral “even more beautifully,” leaving some apprehensive that the process may result in modernist “upgrades” to the nation’s most-visited monument.
