Domaine de la Roche-Jagu

Protecting the Trieux estuary, the château is the last remaining example of a defensive system built between Pontrieux and the Bréhat archipelago. Tradition has it that in the 11th century, a man named Jagu had a motte castrale built, which was gradually transformed into a stone fortress in the 12th and 13th centuries. Destroyed during the War of the Breton Succession (1341-1365), the castle was rebuilt in 1405 for noble dame Catherine de Troguindy, owner of the site, after authorization from the Duke of Brittany Jean V (1389 ? 1442), "with the proviso that the Duke would always have free access to the castle without encroachment from Catherine". Raised to the rank of barony by Duke François II of Brittany in 1487, the land of La Roche-Jagu passed through the hands of several families under the Ancien Régime.
