Occupying a 17C former convent, this museum dedicated to local history has a collection covering the Prehistoric to the 19C (12C-13C enamels, 5C-6C ivories, wood carvings and the famous Stags Tapestry). Antiquity is represented by its Gallo-Roman collection, including the celebrated Lillebonne mosaic, and further additions have been made with recent discoveries such as the bronze statuettes found not long ago in Rouen.
