Paris: After a devastating that engulfed the Notre Dame, the 850-year-old landmark in Paris, President Emmanuel Macron vowed to rebuild the UNESCO world heritage site again.
The fire was brought under control on Tuesday, while the Cathedral's main structure as well as its two towers has been saved, the city's fire brigade has confirmed.
"The fire is completely under control. It is partially extinguished, there are residual fires to put out," media quoted a fire brigade spokesman as saying on Tuesday morning.
Some 500 firefighters worked to prevent one of the bell towers from collapsing, according to fire chief Jean-Claude Gallet, adding that several invaluable artefacts had also been rescued from the burning cathedral.
The fire began at around 6.30 PM, on Monday and quickly caused the collapse of the Cathedral's spectacular Gothic spire and the destruction of its roof structure, which dated back to the 13th century.
Consumed by flames, the spire leaned to one side and fell onto the burning roof as horrified onlookers watched.
Parisians raised their voices in song on Monday night outside the burning Cathedral which is one of the city's most revered historic sites.
French President Emmanuel Macron praised firefighters for saving the Cathedral's iconic facade and towers, saying "the worst has been avoided", media reported.
Yet he lamented the damage already done to "the Cathedral of all French people". He asked the country to commit to rebuilding Notre Dame together, announcing an international fundraising campaign to raise money for the repairs.
"Notre Dame is our history, it's our literature, it's our imagery. It's the place where we live our greatest moments, from wars to pandemics to liberations... This history is ours. And it burns. It burns and I know the sadness so many of our fellow French feel."
A site taking online donations has been launched.
The cause of the fire is not yet clear. Officials have said that it could be linked to the renovation work that began after cracks appeared in the stone, sparking fears the structure could become unstable, media reported.
