Fun facts about Notre-Dame’s construction
- It took nearly two centuries to complete. Work began in 1163 and ended around 1345. Read the full story in our history of Notre-Dame.
- Nobody knows who the first architect was. The original master builder’s name was never recorded.
- It is built from Paris itself. The stone is Lutetian limestone, quarried under what are now the Left Bank’s streets; the old quarries later became the Catacombs.
- The roof frame was called « the Forest ». Its oak beams came from around 1,300 trees; more than 1,000 oaks from French forests were used to rebuild it after 2019.
- It was one of the first buildings with flying buttresses on such a scale, added when the walls started to crack under the vault.
- The spire is a 19th-century addition. The medieval one was removed in the 1780s; Viollet-le-Duc designed a new one in 1859, rebuilt identically in 2024.
Surprising stories
- Point Zero of France is a bronze star on the square in front of the cathedral: all road distances from Paris are measured from it.
- The 28 kings on the façade are not French kings. They represent the kings of Judah, ancestors of Christ, but revolutionaries beheaded them in 1793, believing they were French monarchs.
- Their heads were found in 1977, buried in the courtyard of a Paris mansion, and are displayed at the Musée de Cluny.
- Napoleon crowned himself here in 1804, taking the crown from the Pope’s hands.
- Victor Hugo saved it. His 1831 novel turned public opinion and led to the great restoration of the 1840s–1860s.
- The cathedral was nearly demolished in the early 19th century: it was in such a bad state that its destruction was discussed.
- The rooster on the spire holds relics. The original rooster survived the 2019 fire, dented; the new one, designed as a « phoenix » rooster, contains relics and a document listing the names of the restoration workers.
- The bees survived. Three beehives on the roof of the sacristy came through the 2019 fire intact.
- The fire did not destroy the rose windows. The three great roses, including much 13th-century glass in the north rose, survived.
Bells, music and treasures
- Emmanuel, the great bell of the south tower, was cast in 1686 and weighs about 13 tons. Only Emmanuel survived the melting of the bells during the Revolution.
- There are 10 bells in the towers: eight in the north tower (recast in 2013) and two great bourdons in the south tower, Emmanuel and Marie.
- The great organ has about 8,000 pipes and five keyboards. It was dismantled, cleaned pipe by pipe and reassembled after the fire. Free recitals are held on Sunday afternoons.
- The Crown of Thorns, bought by King Saint Louis in 1239, is kept at Notre-Dame and presented to the faithful on certain Fridays.
- The chimeras are younger than you think. The famous stone monsters on the gallery were added by Viollet-le-Duc in the 19th century. Learn the difference in our gargoyles and chimeras guide.
Notre-Dame in numbers today
- About 11 million visitors in 2025, or 30,000 to 35,000 a day.
- €846 million donated after the fire by some 340,000 donors from 150 countries.
- Entry is free, as for all French cathedrals used for worship. See our reservations guide.
- Disney’s « The Hunchback of Notre Dame » (1996) and the French musical « Notre-Dame de Paris » (1998) both come from Hugo’s novel.
- It is a UNESCO World Heritage Site as part of the « Paris, Banks of the Seine » listing (1991).
