According to the Napoleonic cadastre of Rots, the former Saint-Ouen manor house, very close to the church, included around a quadrangular courtyard the manor house itself, the barn with tithes, various farm buildings and towards the church a pond.
The Barn to the Tithes is the most important building of this complex. The oldest part, dating back to the thirteenth century, is a large rectangular nave oriented from south-west to north-east between two high gables and camped outside overhanging glacis buttresses with lamier; in the center of its south-south droprot wallwest, is pierced the only gate cochere, preceded by a porch (demolished it seems after the protection order!). This very homogeneous part was enlarged to the north-west by an old
This part is private.
As tithing, the abbey of Saint Ouen de Rouen, had built a very large tithing barn. (Around 980, Richard without Fear, Duke of Normandy gives to the abbey of Saint Ouen de Rouen, "the villa called Rots" with all the land that depends on it.)
This barn is located in the heart of a complex consisting of the church of Saint Ouen, the farm of Colombier, in the center of the church district, in a particularly preserved land environment.
