The Parish Church of Our Lady of the Basse Œuvre of Beauvais (French Église Notre-Dame-de-la-Basse-Œuvre de Beauvais), is a church at the west end of Beauvais Cathedral. Dating to the 10th century, it represents the Western end . It is the western end of a much longer church which had been Beauvais's cathedral, and was built in the form of a Roman basilica, a style which still characterized the Carolingian era. The name Basse Œuvre ("Lower Work") dates from the 13th century, and distinguishes it from the Nouvel-Œuvre ("New Work"), the present 12th century Gothic cathedral.
