This ancient tree is said to have the ability to cure boils. Why bother going to the doctor when all it takes is a walk in the woods to heal?

July 25, 1944, shortly after 3 p.m., a Mosquito type plane, a light and fast twin-engine, appeared in the sky of Riaillé, followed a few seconds later by two German fighter planes. Arriving above the hamlet of l'Enclose, one of the fighters gained altitude and dove on the Canadian plane, riddling it with bullets. After starting a curve, the burning Mosquito crashed very close to the Provostière pond. The debris littered the ground for about fifty meters, the fire and the explosion of the ammunition made it impossible to approach. When the fire died down, the inhabitants rushed to the scene and found the charred bodies of the pilot and the navigator. They were identified as Lieutenants Burgess and McPherson. The Germans, who came to the scene, told the mayor that he could bury the bodies but without an official ceremony. However, the occupier's orders were not respected. The bodies were wrapped in sheets and transported to a nearby farm, the village carpentry made the coffins. The next day, a religious ceremony was held in the parish church in the presence of many Riaillé residents and wreaths of flowers covered the coffins. The procession then headed to the cemetery under the supervision of German soldiers who did not intervene. For 80 years, these two Canadian officers have been resting in the Riaillé cemetery. Their tomb is regularly maintained and decorated with flowers by the UNC-Riaillé Mémoire association but also by anonymous people who thus perpetuate the memory of their sacrifice. https://www.echoancenis.fr/actualite-4422-riaille-le-25-juillet-1944-deux-aviateurs-canadiens-etaient-abattus-dans-le-ciel-de-riaille

The wash house is located on the banks of the Erdre, at the exit of the town of Riaillé towards Ancenis. This beautiful building was abandoned for a long time before being restored in 1990-1991. This stone building would have been built around 1850, it measures 20 meters long and 6 meters wide. Today, the site of the wash house is a pleasant place, equipped for picnics as well as a footbridge spanning the Erdre to lead to the Riante Vallée room. https://www.riaille.fr/decouvre/sites-remarquables-et-sentiers-de-randonnee/sites-remarquables-de-la-commune
