Saint-Nicolas Tower

No visit to Hennebont would be complete without taking in its impressive ramparts.The fortified walls stretch for about 1 kilometer—or 0.6 miles—around the old town, making them the second-largest set of defenses in all of Morbihan, just behind those of Vannes. That alone gives you an idea of how important Hennebont once was as a fortified stronghold. The story begins in the late 13th century, when Duke John I of Brittany decided to strengthen this bank of the Blavet.

The mission was clear: protect the people of the town and control this strategic crossing point. But as the centuries passed and the threat of war faded, the walls gradually lost their military purpose. Townspeople began building their houses directly against them, until large sections of the old defenses were almost completely hidden from view.

It wasn’t until the 20th century, when the former defensive ditches were transformed into the Ramparts Gardens, that the walls were opened up again and returned to the spotlight. And now, you’re standing on one of the most impressive parts of that system: Saint-Nicolas Tower. Built in the late 15th century, the tower appeared just as warfare was entering a dangerous new era—the age of artillery and cannon fire.

The builders knew exactly what they were up against, so they gave the tower some serious muscle. Between the gateway and the room inside, the walls are an astonishing 7 meters—or about 23 feet—thick. In other words, they were built to take a beating.

The tower was placed here specifically to defend against cannon fire coming from Mont-Délices Hill, directly across from you. But before you assume everything you see is medieval, there are a couple of twists. The doorway at the base of the tower was added much later to serve a former hotel, cutting through the spot where the original gun emplacement once stood.

And the terrace at the top is a postwar reconstruction. So if you’re up here now, take advantage of it. Pull out your camera, look across the valley, and enjoy a view the medieval guards would have certainly appreciated.
