- For the time that the cathedral was constructed, the crusades took place. Indeed, the third crusade had begun in the cathedral of Notre Dame De Paris.
- The cathedrals in general had constructed because of the religious devotion that happened during this time.
- Notre Dame De Paris was also constructed because Paris became then a politic and commercial centre that it was important that Paris has its own cathedral and that it would be better than of other cathedrals.
- - To show the power of Paris, the Bishop Maurice De Sully had begun the cathedral. Maurice De Sully had seen the first Gothic cathedral, Saint-Denis, and he was impressed.
- - King Louis VII had supported and encouraged the construction of the cathedral, and then it had an advantage on the other cathedrals constructed in this time.
- Napoleon the 1st that returns the cathedral to the cult in 1802 will be consecrated there December 2, 1804. The government of Louis-Philippe, submitted to the pressure of the Romantic Movement embodied by the novel of Victor Hugo titled Notre Dame De Paris (1831), will confide in 1843 the works of rehabilitation of the cathedral to John Le Baptist Lassus and Eugene Viollet-Le-Duc. The first dies in 1857. Viollet-Le-Duc assumes alone the yard until his death, in 1879.

- Since 1992, the progress of technology permits to give back to the outside stone of the Cathedral blackened by the centuries, its original purity and whiteness.
