Abbaye Sainte-Marie du Rivet, Cistercian abbey in Auros, France.

Sainte-Marie du Rivet Abbey is a Cistercian monastery about three kilometres north-west of Auros in the Gironde, reached from the D 10 towards Langon. The nave of the monastery church dates from the 14th century and the cloister survives; the abbey church was listed as a monument historique on 7 January 1926. The buildings stand beside the Rivet stream, a tributary of the Beuve.

A Benedictine monastery probably founded in the Carolingian period, it joined the Cistercian order in 1189 as a daughter house of Notre-Dame de Jouy. A papal bull of Urban IV detached it from the diocese of Bazas and took it under papal protection. Protestants partly burned it in 1593, and it was sold as a national asset on 30 March 1791.

The abbey takes its name from the Rivet, the stream crossing the grounds that feeds the Beuve. Since 1938 it has housed Cistercian nuns of the strict observance (Trappistines) from Blagnac, who moved because of Toulouse airport's construction; the Lourdes-style grotto dug after 1885 helped decide their arrival.

The site welcomes visitors for spiritual retreats, with two lodging areas called Tibhirine and Les Kellia that offer reading rooms and libraries. Planning ahead is recommended to secure a place for a quiet stay.

Louise Ripas, governess of the Tamize family who bought the buildings in 1885, was healed at Lourdes and had a grotto modelled on the Lourdes cave dug at Rivet; a spring broke out during the digging. The same works gave the buildings their medieval look: a tower, a bartizan, corbels and arrow slits.
