The old castle is now partially open to the public. It looks very defensive.

Here, the Blavet meets the Nantes-Brest canal. It was Napoleon Bonaparte, then first consul, who decided on September 17, 1802 to channel the Blavet from Pontivy to Lorient. The project was titanic and lasted more than 30 years.

The Forêt lock is one of the many locks that balance the waters on the Nantes-Brest canal. It is named after the forest of Branguily forest which extends, at this location, on both sides of the canal.

The Château de Pontivy, or Château des Rohan, was built between the middle of the 15th century and the beginning of the 16th century for and by the Viscounts of Rohan. Following the codes of Breton military architecture from the end of the 15th century, this castle is one of the last fortified castles to have been built in Brittany. You will notice that the facade allows adaptation to the development of fire artillery, but that particular attention is paid to comfort and decoration. The downspouts are worked, the skylights carved, and the interior of the castle is equipped with fireplaces and latrines, making it a little gem of comfort for the time. Two permanent exhibitions are housed there: one is dedicated to the sculptor Gaston Schweitzer, while the other is a more contemporary installation by Japanese artist Koki Watanabe. I personally loved the contrast offered by this rather austere facade with the charm of the half-timbered houses in the city center, which I invite you to take the time to discover.

This curved section of the famous Nantes-Brest canal lets you discover the richness of the banks of the Blavet, which flows into the Lorient estuary in Morbihan. You can see that its bed is mainly artificial, and that its course is regulated by an ingenious system of locks. Slightly to the north of Mûr-de-Bretagne, the Guerlédan dam abruptly interrupts its course, thus giving birth to the largest artificial lake in Brittany, the Lac de Guerlédan. The gravelly surface is pleasant for both touring bikes, gravel and even road bikes. I am personally charmed by the melody of the tires on the gravel, so this portion is conducive to meditation and relaxation for me. A real moment of vacation!

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.
