A fire broke out at the Cathedral of Notre-Dame in Paris on Monday evening, according to French authorities and witnesses.
André Finot, a spokesman for the cathedral, said in a telephone interview that the spire of the cathedral had caught fire. The cause of the fire remained unknown.
The fire alarm went off around 6:30 p.m., Finot said, adding the cathedral had been evacuated.
Video filmed by onlookers and shared on social media showed smoke and flames billowing from the top of the cathedral, engulfing scaffolding and the spire.
Firefighters were on the scene, said Finot, who was about 70 feet away from the cathedral.
The cathedral, one of Paris’s most famous landmarks, is currently undergoing renovation work, and several statues were lifted by crane from the spire last week.
“A terrible fire is taking place at the Cathedral of Notre-Dame,” Mayor Anne Hidalgo of Paris said in a tweet, adding that firefighters were trying to bring the flames under control. “I ask everyone to respect the security boundaries.”
