L'Épau Abbey is a former Cistercian abbey founded by the English queen Berengaria of Navarre in 1229. Plans for the abbey were classic with construction respecting the style of other Cistercian buildings. Construction took from 1230 to 1365. Four years after construction began, the Bishop of Le Mans Geoffroy de Laval placed the monastery under the patronage of both Notre-Dame and Saint John the Baptiste. The main buildings were not finished until 1280.
In March 1365, in the middle of the Hundred Years' War, the people of Le Mans burned the building of their own accord. As the monks had left the abbey, the inhabitants feared that enemy troops would seize the building and use it as a base from which to attack the town. In fact, it was the noblemen who forced the people to take action. The church was the part of the abbey to suffer the most damage. However, the following year the bourgeois of Le Mans decided to completely rebuild the damaged parts of the church. But they were not the ones who financed the renovation. Money was difficult to come by in the region and donations to religious orders were rare.
All the damaged buildings were renovated between 1400 and 1444. Charles VI raised finance by taxing the local population. One of the main artisans of the church restoration was Guillaume de Bonneville.
At the beginning of the French Revolution the abbey was transformed into a gigantic agricultural outbuilding.
Between 1965 and 1990, the abbey became popular for cultural functions, in particular for classical music events, conferences and exhibitions. The location is also used as the chair for the departmental assembly, in particular the 18th-century wing, which was restored in 1990.
References:The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
