Le Breuil-Benoît Abbey

Le Breuil-Benoît Abbey (Latin: Brolium Benedicti, French: Abbaye Notre-Dame du Breuil-Benoît) is a former Cistercian abbey in Marcilly-sur-Eure in the Eure department of Normandy, France.

It is located around 10 km to the west of Dreux, on the left bank of the river Eure.

In 1421 the troops of Henry V of England occupied the abbey, set the church on fire, plundered the conventual buildings and killed the monks.

The western walls of the transept remain, as do the five radiating chapels that form the semi-circular chevet behind the choir.

The abbot's house, converted into a gentleman's residence in the 1550s, is also still extant, but most of the other buildings have disappeared.
