What Started Notre Dame Fire
The fire that severely damaged Notre-Dame de Paris began on April 15, 2019. Investigators concluded the most likely cause was an electrical short circuit in the attic area beneath the roof. The blaze started in the early evening and spread quickly through the wooden roof structure.
Timeline and Initial Spread
Fire alarms triggered in the hours before the blaze became visible, but initial alerts were not immediately linked to a major fire. By the time firefighters arrived, flames had already spread across the roof. The fire destroyed much of the roof and caused the iconic spire to collapse within hours.
Damage and Aftermath
The fire caused extensive damage to the roof, spire, and upper walls, though the main stone structure and many artworks were saved. Restoration efforts began shortly after, with safety upgrades and reconstruction work ongoing. Authorities continue to review safety protocols at historic buildings worldwide.
