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

This beautiful water town, famous for its Château des Rohans, is located in Argoat. That is to say in the very center of the Breton peninsula. It is a city which has preserved the Napoleonic memory of the great works carried out during the reign of the emperor. The Blavet is experiencing spectacular floods here which have left their mark on the inhabitants. The most recent ones date from January 1995 and February 2014.

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.

There are 28 locks which allow navigation between Pontivy and Hennebont. These structures, built in the 19th century, are still very important to the many pleasure boats that sail here. The lock keeper moves from one lock to another to allow boats to continue their journey in the Blavet valley.

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.

Just before arriving in Pontivy the river Blavet crashes down a wide cascade, while the canal is channelled left through a lock. Pedestrians and bikers can cross the narrow metal walkway across the barrage and the locks to shortcut to the other side.

The medieval Rohan family, while maintaining their ancestral castle at the town of Rohan, governed the region from Pontivy, where this large castle remains.
