This church was built in the mid-19th century. It can be seen from afar from the surrounding hills, as its size is remarkable for a small village.

The Provostière pond, with a surface area of 73 ha, is connected to the Vioreau lake by the Rigole des Ajaux. This complex is part of the supply system of the Nantes-Brest canal. Its hydraulic management is ensured by the Loire-Atlantique Department, which has owned it since 2008. A 5.5 km path on which a bird observatory is located allows you to go around the pond in about 1h30.

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
