Fire crews are struggling to contain the fire.
The main spire of the historic Notre Dame Cathedral in Paris has collapsed.
Part of the roof has also collapsed.
The historic site, visited by 35,000 people a day, is the most-visited site in Paris, even ahead of the Eiffel Tower.
Authorities have said the fire took place in an area where renovations were happening.
However, the individual in charge of renovations said there were no workmen on the site, which leaves open the cause of the fire.
French Authorities have opened up an investigation.
There are reports of people crying in the streets, as the loss of such an iconic site and pillar of Christianity is an immense tragedy.
