Marmoutier Abbey, also known as the Abbey of Marmoutier (often Marmoutiers), was an early monastery outside Tours, Indre-et-Loire, France. In its later days it followed the Benedictine order as an influential monastery with many dependencies. The abbey was founded by Saint Martin of Tours (316-397), circa 372, after he had been made Bishop of Tours in 371. Martin's biographer, Sulpicius Severus, affirms that Martin withdrew from the press of attention in the city to live in Marmoutier (Majus Monasterium), the monastery he founded several miles from Tours on the opposite shore of the Loire River.
