Square Louise de Marillac,

Square Louise de Marillac honors a woman who fundamentally changed how poverty and illness were addressed in seventeenth-century France. Louise de Marillac co-founded the Daughters of Charity alongside Saint Vincent de Paul, creating a religious order that broke tradition by refusing to be cloistered. Instead of staying behind monastery walls, these women traveled into the homes of the poor and sick to provide direct care. This square serves as a quiet reminder of her legacy as the patron saint of social workers, a role officially recognized centuries after her work transformed the streets of Paris.
