Place de Madame de Montesson

The Place de Madame de Montesson owes its name to Charlotte Béraud de la Haye de Riou, Marquise de Montesson, the morganatic wife of the Duc d'Orléans (1772).
A benefactress of Seine Port, she donated this square, which used to be a jeu de paume. She had four streets dug and many houses built in the village. She was the aunt of Madame de Genlis, Louis Philippe's governess. She left Seine Port after the death of her husband in 1786.
