Maghdouché is a town in the South Governorate of Lebanon. It is located 50 km south of Beirut and 8 km southeast of Sidon. The village lies 3 km inland from the Mediterranean, occupying a hill with elevation ranging between 200 and 229 meters above sea level.

Our Lady of Mantara is a Melkite Greek Catholic Marian shrine in Maghdouché, Lebanon, discovered on 8 September 1721 by a young shepherd. The grotto, which according to a legend dates to ancient times, was subsequently cared after by Monsignor Eftemios Saïfi, Melkite Catholic bishop of the Melkite Greek Catholic Archeparchy of Sidon. The shrine consists of a tower crowned with the statue of the Virgin and Child, a cathedral, a cemetery and a sacred cave believed to be the one where the Virgin Mary rested while she waited for Jesus while he was in Tyre and Sidon. Since its discovery, it has been steadily visited by families particularly each year on the occasion of the feast of the Nativity of Mary on 8 September.
