In the Pontivy court building we found a café with lots of delicious patisserie and other regional specialties. A great surprise in a town that is pretty deserted on Sundays.

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.
