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).

The commune of Pont de la Roque was the subject of a first Allied bombing on April 23, 1944. The bombers targeted the stone bridge built over the coastal river of Siena. Nearly 20 air raids were launched to destroy this bridge and it was not until mid-June that three of the eleven arches were destroyed by bombs.
