An exceptional and unmissable monument: Coutances Cathedral An emblematic monument of the historic capital of the Cotentin region, Coutances Cathedral is, alongside Mont Saint-Michel, the most famous jewel of Norman Gothic architecture.

Coutances Cathedral, with its towers and stone spires, towers majestically above the city, was rebuilt in the 13th century. Nevertheless, the Romanesque structure of the nave and the towers of the facade were retained and form the basic framework of the present cathedral, a masterpiece of Gothic architecture in Normandy. The building owes its fame to its outstanding elegance, the boldness of its lantern tower (the most beautiful in Normandy), and its magnificent medieval stained-glass windows (the largest surviving 13th-century stained-glass windows in Normandy).

Crossed by the GR 223, the Pointe d'Agon lighthouse is a popular destination for hiking. Despite its name, it is a light and not a lighthouse. It is also distinguished by its house which is nowadays occasionally open for visits and exhibitions.
