Abbaye de Nogent-sous-Coucy

Abbaye de Nogent-sous-Coucy is a Benedictine abbey on the right bank of the Ailette River, distinguished by stone arcades from the western gallery of its original cloister. Four arcade sections with buttresses remain visible today, clearly showing the structure of the former monastery.

Founded in 1059 by Albéric, lord of Coucy, and his wife Ade de Marle, the abbey developed into a major religious center in northern France. A 19th-century château later replaced it on the site, though this building was destroyed in 1917.

The site is named after Nogent, referring to its location beneath the Coucy fortress, and the remaining ruins reflect how a major monastic community shaped the region for centuries.

The site sits directly beside Coucy Castle, making it easy to visit both locations together. The grounds are freely accessible and offer plenty of space to explore the visible remains.

The noted chronicler Guibert de Nogent, appointed abbot in 1104, left behind detailed literary and theological writings that provide insight into medieval life. His works remain an important source for historians studying that era.
