Notre Dame Cathedral is a medieval Catholic cathedral and basilica located on the Île de la Cité in Paris, France. Dedicated to the Virgin Mary, it is celebrated as one of the finest early examples of French Gothic architecture. Although neglected and nearly demolished in the 19th century, Victor Hugo's famous novel sparked a public movement that financed its extensive restoration.

By 1831, Notre Dame was in a shameful state of disrepair after decades of neglect and revolutionary damage. Its stained glass had been swapped for plain clear panes, statues were headless, and city officials seriously considered tearing it down.
Parisians viewed the medieval landmark not as a sacred monument, but as a decaying, outdated eyesore.
Victor Hugo published a sweeping romance featuring the cathedral as its actual protagonist to shame the public into caring. The book included lengthy, poetic chapters praising the genius of French Gothic architecture and mourning the loss of the city's heritage.
The novel was a massive sensation, sparking an outcry that forced the government to approve a massive restoration project.
Architect Eugène Viollet-le-Duc took charge, spending decades rebuilding the ruined structure and adding its famous gargoyles. Even the iconic spire that collapsed during the devastating Notre-Dame de Paris fire in 2019 was actually a creation of that 19th-century rebuild.
The cathedral stands today on the Île de la Cité as a masterpiece willed back into existence by a single book.
Notre Dame pioneered architectural techniques that broke away from the earlier, heavy Romanesque style. Builders used rib vaults and external flying buttresses to distribute the immense downward and outward weight of high stone ceilings, allowing walls to be constructed higher and thinner.
Because these structural supports carried the building's load externally, the cathedral's walls could accommodate massive, colorful stained glass rose windows and tall pointed clerestory windows, filling the interior with natural light.
Construction began in 1163 under Bishop Maurice de Sully on the site of an earlier 4th-century church, Saint Étienne, and an ancient Roman temple dedicated to Jupiter. The main structure was largely complete by 1260, but political upheavals repeatedly reshaped its identity.
During the French Revolution in the 1790s, the cathedral was heavily desecrated: bronze, lead, and precious metals were seized to be melted down, and it was temporarily converted into a Temple of Reason and Temple of the Supreme Being. Decades later, it served as the setting for the 1804 coronation of Napoleon as Emperor.
Since 1905, the French government has owned Notre Dame and maintained responsibility for its upkeep, while the Roman Catholic Church holds exclusive rights of use. It functions as the cathedral church of the Roman Catholic Archdiocese of Paris.
The cathedral preserves some of the most famous relics in Christendom, including the Crown of Thorns, along with a sliver and a nail from the True Cross. Following major repairs after the 2019 fire, the Crown of Thorns relic was returned to the cathedral in December 2024.

The French government has owned the cathedral since 1905 and pays for its maintenance. The Roman Catholic Church retains exclusive rights to use the building for worship.
Notre Dame reopened with official ceremonies on December 7 and 8, 2024, following three years of reconstruction. Its Crown of Thorns relic was returned to the cathedral on December 13, 2024.
Before Notre Dame, the site held the 4th- or 5th-century Cathedral of Saint Étienne and the 5th-century baptistery of Saint-John-le-Rond. Artifacts like the Pillar of the Boatmen suggest a Gallo-Roman temple dedicated to Jupiter stood there even earlier.
