International audience ; The abbey of Larrivour (France, Aube), thirtieth daughter of Clairvaux Abbey, is founded in the diocese of Troyes, under the title of Notre-Dame, 9 April 1140 by a colony led by Alain of Flanders. Nothing remains of the buildings of the monastery, sold as national heritage between February 1792 and February 1793, with the exception of an exceptional charter collection and a cartulary, composed c. 1220-30, entered into the Archives départementales de l’Aube during the french revolutionary confiscations (subseries 4H).
