 At the eastern end of the cathedral we come to the apse or the chevet.Radiating apse chapels outside the choir aisle were common in France at the beginning of the 13th century, the complete structure of apse, choir and radiating chapel becoming known as the chevet which can be translated as "headpiece".Famous northern French examples of chevets are in the Gothic cathedrals of Amiens, Beauvais and Reims.
