The Notre Dame de Paris stands on the site of Paris' first Christian church, Saint-Étiennen Basilica, which was itself built on the site of a Gallo-Roman temple to Jupiter. Notre Dame's first version was a "magnificent church" built by Childebert I, the king of the Franks in 528, and was already the cathedral of the city of Paris in the 10th century.

 

Proceeded by a Gallo-Roman temple to Jupiter, a Christian basilica, and a Romanesque church, construction of Notre-Dame de Paris began in 1163 during the reign of Louis VII. Pope Alexander III laid the foundation stone. Construction began in 1163, during the reign of Louis VII, and opinion differs as to whether Bishop Maurice de Sully or Pope Alexander III laid the foundation stone of the cathedral. However, both were at the ceremony in question. Bishop de Sully went on to devote most of his life and wealth to the cathedral's construction.

 

Construction of the west front, with its distinctive two towers, only began circa 1200, before the nave had been completed. Over the construction period, numerous architects worked on the site, as is evidenced by the differing styles at different heights of the west front and towers. Between 1210 and 1220, the fourth architect oversaw the construction of the level with the rose window and the great halls beneath the towers. The towers were completed around 1245, and the cathedral was completed around 1345.

 Construction was completed roughly 200 years later in about 1345.The reigns of Louis XIV (end of the 17th century) and Louis XV saw significant alterations including the destruction of tombs, and stained glass.

 

At the end of the 18th century, during the Revolution, many of the treasures of the cathedral were either destroyed or plundered. Only the great bells avoided being melted down, and the Cathedral was dedicated first to the cult of Reason, and to the cult of the Supreme being. The church interior was used as a warehouse for the storage of forage and food. After falling into disrepair, a restoration program overseen by Lassus (died 1857) and Viollet-le-Duc, was carried out in 1845. This program lasted 23 years, and included the construction of the spire (see image) and the sacristy
