Your path takes you to a cult site, filled with mysticism for thousands of years: Faubouloin. The esotericism of the place has crossed the ages and religions. Water and trees were venerated there (the ash tree by the Celts, the oak by the Gauls). The Druids gathered around a stone to perform their rites, then the Christians replaced the stone with a chapel and Christianised the springs.
The first one on your way, the source of the Ash, is said to cure illnesses and to provide a husband for the young girls who come to ask for one. The second, St Mary's Fountain, was consulted as an oracle by the mothers of sick children: if the small garment thrown into the water floated, healing was near. If not, it was a sign of death...
Finally, the last one, the Fountain of St. Margaret, was called upon for happy deliveries.
The first chapel on the site dates from the 11th century and is known as the Faubouloin chapel, the Ash tree chapel or the Notre Dame de Grace chapel (listed as a historic monument since 1943). It was the scene of many pilgrimages, therapeutic rites and prayers to influence the rain (drought or flood). A mass is always celebrated there on 15 August
