Murbach Abbey was a famous Benedictine monastery in a valley at the foot of the Grand Ballon in the Vosges. The monastery was founded in 727 by Eberhard, Count of Alsace, and established as a Benedictine house by Saint Pirmin. Its territory once comprised three towns and thirty villages. The buildings, including the abbey church, one of the earliest vaulted Romanesque structures, were laid waste in 1789 during the Revolution by the peasantry and the abbey was dissolved shortly afterwards.
Of the 12th-century Romanesque abbey church, dedicated to Saint Leodegar (St. Léger), only the transept remains with its two steeples, and the east end with the quire. The site of the nave now serves as a burial ground. The building is located on the Route Romane d'Alsace.
References: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).
