In 1684, Louis XIV laid the first stone of a new building: the parish of Notre-Dame which gave its name to the district. The inhabitants of old Versailles, the Parc aux Cerfs and the nearby streets, numbering about four thousand and fifty, no longer had any place of worship. Notre-Dame was far and its access difficult, since it was then necessary to cross the place of arms to get there. When, at the end of the seventeenth century, this part of the city took extension, the architects in charge of drawing up the plans did not fail to provide a church By decree of Charles Gaspard Guillaume de Vintimille du Luc, archbishop of Paris, on June 4, 1730, a chapel was erected as a parish under the patronage of Saint Louis. The inhabitants had to settle for this chapel for several years. Yet they were increasingly numerous. Finally, around 1740, a resolution was made to build a real church. There was a vast square there that seemed perfectly suited to this destination. Louis XV appointed in May 1742 Jacques Hardouin-Mansart de Sagonne, grandson of the architect of Louis XIV, to the great dissatisfaction of Ange-Jacques Gabriel, official architect of the king who hoped to receive the order. It was blessed on August 25, 1754, the day of Saint Louis, and chosen as a cathedral at the creation of the bishopric of Versailles in 1802. It was not consecrated until 1843. It was classified as a historical monument on October 30, 1906
