The exhibition reveals the history of the Saint-Ouen manor house in Rots, as detailed in the Napoleonic cadastre. This manor house, located near the church, comprised a quadrangular courtyard with the Tithe Barn as the main building. Probably dating from the 13th century, the barn is a large rectangular nave supported by buttresses, with a single carriage entrance. Formerly owned by the Abbey of Saint-Ouen de Rouen, it is part of a preserved ensemble with the Saint-Ouen church and the Colombier farm.
