Rue de Caumartin

The Rue de Caumartin in the 9th arrondissement of Paris received its name from Antoine-Louis Lefebvre de Caumartin, marquis de Saint-Ange, Comte de Moret (1725-1803), who was prévôt des marchands (1778-1784). He gave the authorization to open the street on 3 July 1779. Opened in 1780, the street extended from the rue Basse-du-Rempart located at the foot of the rampart (now Boulevard des Capucines) to rue Neuve-des-Mathurins through land acquired from the priests mathurins by Charles-Marin Delahaye, general-farmer. Further on the north, was the small street Thiroux opened in 1773 by President Thiroux of Arconvillé. And the small rue Sainte-Croix opened further on the north in 1780 through marshes and fields. The Rue de Caumartin absorbed them on 5 May 1849.[1]

The French architect Aubert built 28 mansions in the area, including the n°1 and n°2, on each side of the street at the beginning and the junction with the Boulevard des Capucines. They were decorated with figures in half relief, small amours, medallions, and various ornaments. Both included an outside rotunda on the street.[1]
