This spring, known as "de la demoiselle", is around fifty metres from the Roman road. It was already used in ancient times, as it was an important watering place for horses and oxen before they started to climb the slope. We don't know the origin of its name, but there are three possible explanations: the name of the person who lived in the forest house, the name of an insect similar to the dragonfly, only smaller, or in the sense of a fairy, as we sometimes see, a name that in some cases may have revealed the presence of archaeological remains. The spring is located at the geological boundary between limestone and impermeable marl with ostrea acuminata (small oysters) and is the outlet of the water table formed by rainwater seeping into the cracks in the plateau. The water that gushes out is pure, its flow variable but uninterrupted throughout the year. The large, pear-shaped stone pool is a contemporary addition to the forest house above.
