The Notre-Dame-d'Oulmes priory is first mentioned in 1326. Three parts of the priory have been preserved: the ruined church, flanked by a chapel; a long rectangular building wing to the north; and another building wing arranged perpendicular to it in the west, separated from it by a portal. The ruins of the church, including the south chapel, as well as the façades and roofs of the convent buildings of the Notre-Dame-d'Oulmes priory were protected as historical monuments by decree of 14 November 1980.
In the vicinity of Nuaillé-sur-Boutonne lies the Église Saint-Germain de Varaize church. In the wider regional area around Nuaillé-sur-Boutonne lies the Eglise Saint-Pierre de Frontenay-Rohan-Rohan church.
Nature
The Boutonne forms the western boundary of Nuaillé-sur-Boutonne. The Brédoire, a 14.3-kilometre-long tributary of the Boutonne, also runs through the town. Poplar cultivation became established in Nuaillé-sur-Boutonne at the beginning of the 20th century. The local poplar stands are located along the Boutonne in wet and frequently flooded habitats.
The Les Pêcheurs Angériens association is responsible for the management of the fishery and the protection of the aquatic habitats of the Boutonne from Nuaillé-sur-Boutonne to the Houmée near Tonnay-Boutonne.
