Josselin Castle

Josselin Castle (Château de Josselin) is a fortified castle in the town of Josselin in Brittany, France, that overlooks the River Oust. It has medieval origins and later Renaissance and classical modifications associated with the Rohan family.

The site presents a prominent riverside silhouette of towers and ramparts and offers interior rooms and chapel spaces open on guided visits. Visitors commonly view the exterior from riverbanks and town promenades and explore parts of the castle interiors that preserve family and regional history.

The castle’s defensive keep, towers and facades show construction phases spanning the medieval and early modern periods, and the surrounding gardens and town setting add to the visitor experience. Seasonal opening times apply for interior access and guided tours.

Originally constructed in the medieval era and expanded and remodeled over subsequent centuries, the castle became the seat of the Dukes of Rohan and underwent restorations that introduced Renaissance features and later decorative work. Ownership and functions evolved, but the site retained its role as a regional noble residence.

Located in the center of Josselin in Brittany, the castle stands on the banks of the River Oust and is accessible from nearby regional towns and roads in Morbihan.
