Notre-Dame de Paris,is a medieval Catholic cathedral on the Île de la Cité in the fourth arrondissement of Paris. The cathedral is widely considered to be one of the finest examples of French Gothic architecture.
The cathedral was begun in 1160 and largely completed by 1260, though it was modified frequently in the following centuries. In the 1790s, Notre-Dame suffered desecration during the French Revolution when much of its religious imagery was damaged or destroyed. Soon after the publication of Victor Hugo's novel The Hunchback of Notre Dame in 1831, popular interest in the building revived. A major restoration project supervised by Eugène Viollet-le-Duc began in 1845 and continued for twenty-five years. 12 million people visit Notre-Dame yearly, which makes it the most visited monument in Paris.
