Beauvais, Saint-Pierre

The Cathedral of Saint Peter of Beauvais (French: Cathédrale Saint-Pierre de Beauvais) is an incomplete Roman Catholic cathedral located in Beauvais, in northern France. It is the seat of the Bishop of Beauvais, Noyon and Senlis. It is, in some respects, the most daring achievement of Gothic architecture, and consists only of a transept (sixteenth-century) and choir, with apse and seven polygonal apsidal chapels (thirteenth century), which are reached by an ambulatory.

The small Romanesque church of the tenth century, known as the Basse Œuvre, much restored, still occupies the site destined for the nave.
