Moyenmoutier abbey was founded by Saint Hydulphe in 671. In 915 the abbey was pillaged and torched by a Hungarian raiding party; it was rebuilt around 960. In the 12th century Aubert of Paroye built a hilltop castle on the Rock of St Peter, but this was destroyed in the 13th century under orders from the Duke of Lorraine.
The monastery dominated local life, sharing the ups and downs of the ensuing centuries with the little town that surrounded it. By the end of the 16th century, with the religious world across western Europe undergoing the confrontation between the Protestant winds from Germany and the Counter Reformation forces confronting it, there was a feeling that monasticism in Moyenmoutier had fallen into a sorry state. The commendatory abbot of Moyenmoutier, Eric of Lorraine who was also the Bishop of Verdun and commendatory abbot of the Monastery of St Vanne in Verdun, undertook to restore a more orderly existence to the monks under his authority. He entrusted the task to Dom Didier de La Cour. In 1604 the resulting new constitution of the Congrégation of St. Vanne and St. Hydulphe received papal approval. The reforms became an important element in the Counter Reformation, being copied by other Catholic religious houses and congregations including in 1621, most famously, the Congregation of St. Maur.
The 18th century was a golden age for the Abbey at Moyenmoutier which for many years numbered among its scholars of philosophy and theology Dom Augustin Calmet, who in 1728 went on to become abbot at Senones. The French Revolution called time on the monastic existence, however, and in 19th century Moyenmoutier the chanting of monks was replaced by noise of industrial machines.
The elegant simplicity of Moyenmoutier church, which has the dimensions of a cathedral, contrasts with its exceptional furniture, in particular the organ and 17th century choir stalls.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
