French authorities are yet to confirm what started the fire, however local media report the flames may be linked to a renovation project on the church spire.
Parisian fire chief Jean-Claude Gallet said the iconic towers had been saved from the blaze, as authorities state the structure was saved from 'total destruction'.
One fire-fighter has been seriously injured while two-thirds of Notre Dame's roofing was destroyed.
The extent of the damage to the rest of the cathedral is still unclear.
'We’re still working to save the cathedral’s work of arts,' Laurent Nunez, secretary to France’s interior minister, told reporters on Monday.
French president Emmanuel Macron addressed world media only hours after the last flames were extinguished.
He vowed to 'rebuild' the centuries-old Parisian cathedral and praised the firefighters for saving the landmark towers.
'We will appeal to the greatest talents and we will rebuild Notre-Dame because that's what the French are waiting for, because that's what our history deserves, because it's our deepest destiny,' Mr Macron said.
More to come.
