L'Étanche Abbey is a former Premonstratensian monastery founded in the 12th century, the ruins of which are near the modern village of Deuxnouds-aux-Bois, in the commune of Lamorville.
The abbey of Notre-Dame de l'Étanche was founded in about 1144 by Philippe, abbot of Belval, in a secluded valley then known as Faverolles, near Deuxnouds-aux-Bois. The first patrons of the foundation were Albéron de Chiny, bishop of Verdun, and Bertrand le Loup and his nephew Albert, seigneurs of Faverolles, in whose lands the community was settled. The abbey church was consecrated in 1147. The earliest existing charter dates from 1157.
Nearby there was at first a Premonstratensian convent, which was dissolved in time. The modest abbey possessed a priory at Benoîte-Vaux, a famed place of pilgrimage in Lorraine.
The structures were utterly destroyed by the Swedes in 1632, during the Thirty Years' War, and were not rebuilt until 1743, with nine monastic cells in a range. The chapel was completed in 1770. Three abbés of L'Étanche were of note: Dom Dominique Callot, a student of chemistry and heraldry; Dom Edmont Maclot, author of pious works; and Dom Jean François Joseph Boucart, who assembled a collection of medals and a prestigious library, since dispersed.
References:Dryburgh Abbey on the banks of the River Tweed in the Scottish Borders was founded in 1150 in an agreement between Hugh de Morville, Constable of Scotland, and the Premonstratensian canons regular from Alnwick Abbey in Northumberland. The arrival of the canons along with their first abbot, Roger, took place in 1152.
It was burned by English troops in 1322, after which it was restored only to be again burned by Richard II in 1385, but it flourished in the fifteenth century. It was finally destroyed in 1544, briefly surviving until the Scottish Reformation, when it was given to the Earl of Mar by James VI of Scotland. It is now a designated scheduled monument and the surrounding landscape is included in the Inventory of Gardens and Designed Landscapes in Scotland.
David Erskine, 11th Earl of Buchan bought the land in 1786. Sir Walter Scott and Douglas Haig are buried in its grounds.
