French President Emmanuel Macron pledged to rebuild Notre Dame as the historic cathedral continued to burn in a blaze that could last days.

“I say this to you solemnly this evening: we will rebuild this cathedral. All together,” Macron said in a televised address.

“And it is certainly a part of our destiny as France and our project for years to come.”

Macron thanked the hundreds of firefighters working to put out the inferno, adding that they will continue to battle the blaze “for hours and several days.”

A fundraising effort will be launched nationally on Tuesday, Macron announced, adding that he would seek help internationally.

“We will call on the most talented people,” from around the world, Macron said, standing in front of the still-burning landmark.

“We will rebuild because it is what the French people expect, because it is what our history deserves,” he continued. “Because it is our profound destiny.”

Authorities say the structure of Notre-Dame has been saved, though much of the 850-year-old cathedral’s roof and its spire have been destroyed.

“The worst has been avoided but the battle isn’t fully won yet,” Macron said. “In the next few hours there will be difficult circumstances but thanks to [the firefighters’] courage the facade and the two main towers of the cathedral have not collapsed.”
