Château de La Roche-Jagu
Castle near Saint-Malo

Château de La Roche-Jagu is one of the top attractions in Ploëzal, a commanding 15th-century fortress perched high above the Trieux River. Built to control movement along the waterway, its austere stone façade, defensive corridors, and elevated position reveal its strategic purpose. Yet today, the château is equally admired for its cultural programming and expansive gardens, making it a destination where history, landscape, and artistic expression all converge.
Since being taken over by the Departmental Council of Côtes-d’Armor in 1958, the château has been beautifully restored and reimagined as a vibrant cultural venue. Seasonal exhibitions, concerts, and public events draw visitors from across Brittany, while its permanent exhibition, Si La Roche-Jagu m’était contée, provides vivid insight into medieval life. Its setting amid 30 hectares of themed gardens makes it a highlight of any walking tour of Ploëzal, especially for travelers who love architecture and nature in equal measure.

History and Significance of Château de La Roche-Jagu
Constructed in the 15th century, Château de La Roche-Jagu played a critical role in monitoring the Trieux River, a vital artery for trade and communication. Its fortified design-with machicolations, narrow windows, and walkways-reflects the concerns of a region where political power and control over waterways were essential.
Over the centuries, the château endured periods of neglect and change, but its strategic location ensured its continued importance. In 1958, the Côtes-d’Armor Departmental Council acquired the estate and undertook major restoration work in 1968. This initiative preserved the structure’s medieval integrity while opening it to the public as a cultural and historical landmark.
Today, the château’s permanent exhibition immerses visitors in the daily life of a Breton seigneurie, illustrating domestic routines, social hierarchy, and medieval craftsmanship. Combined with rotating exhibitions and performances, the site balances heritage preservation with contemporary cultural engagement.
