Sens Cathedral

Sens Cathedral is a Catholic cathedral in Sens in Burgundy, eastern France. The cathedral, dedicated to Saint Stephen, is the seat of the Archbishop of Sens.

Sens was the first cathedral to be built in the Gothic architectural style. The choir was begun between 1135 and 1140, shortly before Notre Dame de Paris. The sanctuary was consecrated in 1164, but work continued until 1176. It is a national monument of France. The structure was completed in the late 15th–early 16th century with Flamboyant style transepts and a new tower. The architecture of its choir influenced that of Canterbury Cathedral, rebuilt in Gothic style by the master mason William of Sens.
