Metz Cathedral or St. Stephen's Cathedral in Metz (Cathédrale Saint-Étienne de Metz), in the département of Moselle, France, is the seat of the Bishop of Metz. It was formed in the 14th century by joining together two churches: the nave of Saint-Etienne, built in the 13th century, was attached to the north side of an older Romanesque church. It is found in the heart of the city, on the Place d'Armes, where it provides a focal point for the "centre ville".
In the 15th century, a transept and a choir were added. This nave is the third highest in France with its 41.41 meters. Only Beauvais Cathedral and Amiens Cathedral are higher.
