Kervezo lock on the Nantes-Brest canal

Highlight • Other

Ancient canal locks just before the confluence with the Rigole d'Hilvern. Both are accompanied by excellent tow-path bike trails. The Vélodyssée follows the Canal de Nantes à Brest.

Charming small town on the banks of the river Oust and the Canal from Nantes to Brest which merge for part of the way. It is the home to the House of Rohan, members of which included viscounts, dukes and princes and has had a prominent role in French history. The name of the commune and it's coat of arms are identical to that of the family. Murals and historic buildings tell the story. There is also a helpful visitor center.

Château de Josselin seen from the Sainte-Croix bridge

Highlight • Castle

Erected at the beginning of the 11th century, the Château de Josselin was once just a simple wooden building. Rebuilt and extended over the centuries, it was modernized by the Rohan family who still live there today.

The castle can be visited and also houses a museum of dolls and toys.

Josselin Castle

Highlight • Religious Site

The castle's imposing towers are reflected in the River Oust. Owned by the Rohan family, one of the oldest families in Brittany, it is the symbol of this pretty town. Plan half a day to stroll through the charming streets of this "petite cité de caractère" (small, particularly picturesque town) and also visit the basilica.
