Abbey of Monthiers-en-Argonne

A daughter house of Trois-Fontaines and of the lineage of Clairvaux, it was dedicated to Saints Nicholas and Mary (Notre-Dame).

It was founded at the site called "Vieux Montiers" (Old Monastery) by its first abbot, Eustache, around 1135.

Originally a house of Augustinian canons, it adopted the Cistercian rule on 30 May 1144.

Eustache was assisted by a co-abbot, Gervais, and together they greatly expanded the abbey's temporalities.

It had lands and farms in Guidonval, La Basse-Cour, Rotonchamp, Valdivière, Le Saussy, Hurtebise, Bronne, Bouët and Outrivière in Noirlieu, Épensival in Épense, Lalieue in Remicourt, Notaval and Letemple.

The abbey is in the top right corner of this map, on the edge of the forest of Argonne
