Louis XIV chose this place as the centre of brass and woodwind instrument manufacture. In the 19th century, painters were attracted to the town, particularly Corot, whose paintings of the bridge and the cathedral are celebrated. Prokofiev spent the summer of 1920 there orchestrating the ballet Chout. Originally officially called Mantes-sur-Seine (meaning "Mantes upon Seine"), Mantes merged with the commune of Gassicourt in 1930 and the commune born of the merger was called Mantes-Gassicourt. On 7 May 1953, the commune of Mantes-Gassicourt was officially renamed Mantes-la-Jolie (meaning "Mantes the pretty"), allegedly in reference to a letter of King Henry IV addressed to his mistress Gabrielle d'Estrées who resided in Mantes: "I am on my way to Mantes, my pretty"
