Legend has it that Saint Radegonde gave this fountain to the people of Riantec as thanks for having hidden her and protected her from the wrath of her husband Clotaire 1st, king of the Franks of Soisson. The spring is said to have sprung from the footsteps of Saint Radegonde's horse as she fled from her royal husband. The site was located on the ancient Gallo-Roman road leading to Port-Louis.
