After being dissolved in the French Revolution it became in the 1830s the mother house of the Sisters of Christian Schools of Mercy, now the Congregation of Saint Marie-Madeleine Postel.
Jacques Le Febvre du Quesnoy, Bishop of Coutances and abbot of Saint-Sauveur, died at the abbey and was buried in the chancel of the church.
The bailiff Hector Louis Amédée Ango, grandfather of Barbey d'Aurevilly, thought to protect the abbey church by transferring the parish service to it, but his plan was opposed by the constitutional priest Fr.
In 1832 Mother Marie-Madeleine Postel (later canonised) was able to buy the abbey ruins that she wanted to make the parent of the congregation that she had founded in Cherbourg.
There then remained only two small low houses to the left of the church and the entrance porch and the lower part of a building that had served as a cellar and storeroom.
Undeterred, Mother Marie-Madeleine Postel, despite her advanced age, undertook to rebuild the entire building by entrusting the work to François Halley, a local architect and sculptor.
