The Église Notre-Dame, a ruin, is attributed partly to twelfth century and partly
Renaissance style. It became a historical monument on 18 November 1919. The
Abbaye Notre-Dame d'Igny was founded in the 1120s by monks from the Abbey of Clairvaux, sent by St. Bernard of Clairvaux. Following a pilgrimage to the abbey which brought rapid development, a daughter house,
Signy Abbey, was founded in 1135. The second abbot,
Guerric of Igny, was raised to the rank of
Blessed; his
relics are still venerated in Igny. At the time of the
French Revolution, the religious community was dispersed. It was rebuilt in 1780. Monastic life resumed in 1876 with the support of the
Diocese of Reims. Destroyed in 1918, the abbey was rebuilt in 1929 and occupied by a community of nuns from Laval. ==Population==
