Rue de Sévigné is a  historic street located in the heart of Le Marais, Paris, crossing the 3rd and 4th arrondissements. It dates back to the 15th century and was named in 1867 after Marie de Rabutin-Chantal, Marquise de Sévigné, a famous 17th-century French letter writer who lived nearby. The street is known for its picturesque, medieval Parisian ambiance, having escaped major 19th-century renovations. It overlooks the Église Saint-Louis-Saint-Paul church.
 
The church is Baroque-style built between 1627 and 1641 by Jesuit architects Étienne Martellange and François Derand, with financial support from Louis XIII. It was the first church in Paris to fully embrace the Baroque style instead of the Gothic. Madame de Sévigné attended this church.
 
Marie de Rabutin-Chantal, marquise de Sévigné (1626–1696) is an interesting female blazetrailer of her time. She was a renowned French aristocrat and one of the most celebrated letter-writers of the 17th century. Born in Paris to an old Burgundian noble family, she was orphaned young and raised by her uncle, receiving an exceptional education for a woman of her time.
She married Henri de Sévigné in 1644 and had two children, Françoise-Marguerite and Charles. Widowed at 25, she devoted herself to her children and became a prominent figure in Parisian society and literary salons.
Madame de Sévigné is best remembered for her extensive correspondence—especially with her daughter—offering vivid, witty, and insightful accounts of French court life, society, and historical events during the reign of Louis XIV. Her letters, totaling nearly 1,800, are considered masterpieces of French literature and a valuable window into the culture and politics of her era
