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.
During the Commune of 1871, the Cathedral was nearly burned by the Communards - and some accounts suggest that indeed a huge mound of chairs was set on fire in its interior. Whatever happened, the Notre Dame survived the Commune essentially unscathed.
Now in 1991, a 10 year program of general maintenance and restoration has begun, and sections of the structure are likely to be shrouded in scaffolds for the foreseeable future.
