The castles of Brittany
Fortresses of the dukes, border strongholds and manor houses: which ones to visit, and what they tell us about an independent duchy.
7 min read
Breton castles do not look like those of the Loire, and it is a matter of history: Brittany was an independent duchy until 1532, surrounded by a more powerful neighbour. Its castles are therefore fortresses before they are homes, built of granite, squat, and often set on a border or a coast.
The most visible line of defence runs along the Vilaine and the Rennes area: Fougères, Vitré and Châteaubriant watched over the march between Brittany and France. To the west, it was the coasts that had to be held, against the English and then against everyone.
The fortresses of the march
Fougères is the most impressive: thirteen towers over two hectares, encircled by the Nançon, and the largest medieval fortress in Europe in this state of preservation. The towers tell of three periods: the oldest are square, the next round, the last horseshoe shaped. It takes two hours to visit, wall walk included, and you can see it from above from the public garden, which is worth the trip on its own.
Vitré, thirty kilometres away, is better preserved within its town: the castle stands at the end of a whole street of half timbered houses, making one of the most complete medieval ensembles in Brittany.
The coastal castles
Fort La Latte, near Cap Fréhel, sits on its own rock, separated from the land by a chasm crossed on a drawbridge. Suscinio, on the Rhuys peninsula, was the summer residence of the dukes, on the edge of the marshes. The castle in Saint-Malo now houses the town hall and a museum.

What to know before you visit
The heritage around them
A castle is never visited alone: it has a town around it, and that is often what makes the trip worthwhile. The parish closes of Finistère, the medieval towns of Dinan and Guérande, and the manor houses of the Trégor complete what the fortresses tell.

1532, the date that explains everything
The 1532 treaty of union joined the duchy to the kingdom of France, in exchange for keeping its privileges: its Estates, its Parliament, and exemption from the gabelle, the salt tax, which still explains salted butter today. The fortresses then lost their military purpose, and many were dismantled or left in ruins, which is the form in which you visit half of them.
