#NotreDameCathedralFire: Cause of devastating blaze revealed

The cause of the devastating Notre Dame fire has been revealed, and investigators feel it was caused by an electrical fault.

The historic building went up in flames on Monday as tearful Parisians watched in despair.

More than 400 firefighters battled the flames to save the main structure and towers.

Police have earlier this week opened an investigation into the devastating fire, questioning a firm of “Cathedral Restorers” to establish how it all started.

Craftsmen from Le Bras Freres were working on the 850-year-old iconic building before the fire took hold.

Paris public prosecutor Remy Heitz said his office was “favouring the theory of an accident”.

But he had assigned 50 people to work on what he believed would be a “long” and “complex” investigation.

It was reported that the high altar, installed in 1989, was the only piece of architecture inside the building that was damaged.

It was hit by the cathedral’s spire when it came crashing down in the flames.

Three “irreplaceable” rose windows which date to the 13th century, at first feared to have exploded, are still intact.

Based on where in the building the flames started, initial speculation suggested restoration works could be responsible for the blaze.

While the cause of the fire has now been identified, the official added the “green light” is yet to be given for work to begin on the Cathedral for safety reasons.

Police have warned there “important risks” of collapse and falling objects remain.

President Emmanuel Macron has vowed to rebuild the damaged Cathedral within five years and has said it will be rebuilt “even more beautifully” than before.
