The history of the Grange aux Dîmes and its restoration have been particularly detailed and illustrated. It is to a Ouistrehamais: Mr. Louis Hugues, architect, that the City has entrusted this restoration whose work will last from 1986 to 1988. In the heart of its ancient village which has preserved a remarkable medieval heritage, the Grange aux Dîmes is part of a beautiful set of rural buildings of monastic origin, recently restored. It was part of the Farm of the Abbey or the Barony, property of the Abbess patroness of Ouistreham. This barn, which is mentioned for the first time in 1257, was abandoned during the so-called Hundred Years War period and rebuilt in the fifteenth and sixteenth centuries using original elements, to resume its function. Until the Revolution, Ouistreham was an ecclesiastical, legal and fiscal dependency of the Abbey to the Ladies of Caen whose Abbess received the tithe (tax in kind representing about the tenth of the harvests, peaches and herds) stored in the barn provided for this purpose.
A monastic barn until the French Revolution, it retained its functions as a barn in the service of a private layman until 1971, the date of the purchase by the City. The barn is registered under the title of Historical Monuments, by decree of October 11, 1971. In 1984 and 1985, the first restoration works were undertaken. They concern the development of the surroundings of the barn and the demolition of adjoining outbuildings.
