1The kings who lost their heads
In 1793 revolutionaries pulled down the 28 statues of kings on the facade, thinking they were kings of France; they were kings of Judah. Many heads were found in 1977, buried in a courtyard nearby, and are now in the Musée de Cluny.
2Saved by a novel
By the 1830s the cathedral was in ruins. Victor Hugo's novel "The Hunchback of Notre-Dame" (1831) made Parisians care again, and Viollet-le-Duc restored it, adding the spire and many of the gargoyles you see.
3The fire and the rebuild
On 15 April 2019 a fire destroyed the roof and the spire. It took five years and about 2,000 craftspeople to rebuild them, using oak and techniques close to the medieval ones; the cathedral reopened on 7 December 2024.
