Sens Cathedral (French: Cathédrale Saint-Étienne de Sens) is a Catholic cathedral in Sens, Bourgogne, eastern France. It was one of the earliest Gothic buildings in the country, and the largest of the early Gothic churches. The choir was begun in 1140. As was typical in cathedral construction work progressed westwards, building the nave, with the west front completed around 1200. The structure was finally completed in the 16th century. The architecture of its choir influenced, through the architect William of Sens, that of the choir of Canterbury Cathedral.
