Saint-Cyran's origins lie with a monastic foundation founded by Saint Sigiramnus (Cyran) in the 7th century.[3] The foundation was first known as Saint-Pierre de Longoret (Longoretum, Lonrey) but was later named after its founder.[3] In the 17th century, Jean du Vergier de Hauranne, known as the Abbé de Saint-Cyran, served as abbot of this monastery. He was succeeded by his nephew Martin de Barcos. The monastery was dissolved in 1712.[3]
