In the 14th century the abbey suffered badly from the effects of the Hundred Years' War; large gifts from Gaucher V de Châtillon enabled it to rebuild in 1378.

In 1790 all religious houses in France were suppressed; in April 1791 the six monks then living there were turned out and the abbey's assets were declared national property and sold off.

[7] The monastic premises passed into private hands but in 1876 were reacquired by the Archdiocese of Reims for the establishment of a Trappist monastery by a community of monks from the Abbey of Sainte-Marie-du-Désert.

Just before the Second Battle of the Marne in May 1918 the buildings were evacuated; when retreating on 6 August 1918, the Germans blew them up, destroying the entire abbey with the exception of the small library.

[8] In 1955 Igny founded the first house of Cistercian nuns in Africa, the Abbaye Notre-Dame de la Clarté Dieu at Murhesa in South Kivu, in the Democratic Republic of the Congo.
