La Roche-Derrien

Tourism, holidays & weekends guide in the Côtes-d'Armor

La Roche-Derrien is a commune in the Côtes-d'Armor department in Brittany, located 17 km east of Lannion and about 10 km from the coast of the English Channel and the Côte d'Ajoncs.

The geography of the site, a rocky promontory overlooking the bottom of the Jaudy estuary, where tidal sea water mingles with the fresh water of the coastal river, explains the history of the territory. From the Gallo-Roman period it became a castle town before a castle was erected in the Middle Ages, with a defensive purpose, to prevent any maritime invasion and to protect the first commercial exchanges. In 1347, however, during the war of succession to the duchy of Brittany, the troops of Jean de Monfort, allied to the English, won a decisive battle at La Roche-Derrien over those of Charles de Blois, allied to the French. Later the famous Du Guesclin receives in reward of services rendered to the king of France the lordship of La Roche-Derrien and would have come to settle there. However, the prosperity of the city remains, considered until the middle of the twentieth century as one of the most active in the historical region of Trégor (Shops, slate, flax work). Its historical and authentic heritage in the heart of a territory with the preserved environment makes La Roche-Derrien, which has a good thousand inhabitants and has been labeled "Small City of Character", a pleasant stage.

Things to see and do

A discovery of the locality goes through a walk in the medieval heart of the city. The names are evocative ("place of the pillory", "alley of the English"...) and one can still admire there many half-timbered houses of wood of the 15th, 16th and 17th centuries.

At the top of the old feudal mound, a viewpoint on the Jaudy estuary and the loop of its upstream course is not to be missed.

Continue the visit of La Roche-Derrien by the church of St. Catherine of Alexandria, classified. In the Romanesque and Gothic style, its oldest parts date back to the 13th century. The important surface of the choir and the suite of chapels made it in its time an edifice in the measure of its lords. Inside, the stained-glass windows recount two episodes in the history of the city: the martyrdom of his patron Saint Catherine of Alexandria and the capture of Charles of Blois during the battle of 1347. The organs would come from the abbey From Westminster to London after passing through the cathedral of Saint-Brieuc. Restored from 1992 to 2002, they contain the oldest pipes of Brittany. Free visits between 10am and 6pm. Continue by La Maladrerie, a hospital founded in the 13th century by Geoffroy, Lord of Kersaliou, on his return from the crusade. A large high chapel on the second floor served as a courtroom for the seneschals and disappeared in the 19th century. Its remains are integrated in the building which now hosts the Tourist Office. The new facilities have preserved the medieval spirit of the place.

Also worth seeing is the Chapelle du Calvaire on the feudal mound, on the site of the old donjon, as well as the chapel Saint-Jean, erected in the 12th century by the Templars, and the Notre-Dame A pity that reminds passersby of the famous battle of 1347.
