These before and after photos show the extent of the damage at one of Paris’ most recognizable landmarks.
The fire left the building blackened by smoke and destroyed the cathedral’s iconic spire, which was reconstructed in the 19th century. The roof was also destroyed.
It is believed that the cause of the fire was related to a renovation project being carried out at the cathedral. Investigators have ruled out arson and terrorism.
World leaders have been expressing their solidarity with France in the wake of the blaze, AP reports. U.S. President Donald Trump called the cathedral “one of the great treasures of the world.” Pope Francis, Japanese Prime Minster Shinzo Abe, and Russian President Vladimir Putin all expressed their sadness, AP said.
