The current slows, the right bank bristles with brown rooftops, and a square castle appears above the plane trees: this is La Voulte-sur-Rhône, on the Ardèche bank, halfway along the major river itineraries between Lyon and Avignon. River boats moor at the very foot of the old town, and the port call is savoured just as the town presents itself: without ceremony, with a surprising wealth of stories for a few thousand inhabitants.

The Climb to the Castle

From the landing, a few minutes are enough to reach the narrow lanes of the castle town, which wind their way up to the seigneurial residence. Built from the 13th to the 17th century, the complex was home to the Bermond d'Anduze family, lords of the area from 1251, then to the Lévis family, allied with the Ventadours, before passing to the Rohan-Soubise family until the Revolution. Purchased by the town in 1962, it is gradually being restored; its terraces open wide views over the river and the hills of the Drôme on the opposite bank. Along the way, you pass the Giroud fountain and vaulted passages where the shade keeps the coolness of the old walls.

The Princes' Chapel

The site's treasure is hidden within the walls: the Princes' Chapel, built around 1487 and listed as a historic monument since 1923. Beneath its rib vaults, the decoration is surprisingly delicate: a depiction of the Resurrection of Christ, medallions of the Evangelists, angels' heads and garlands of flowers, blending Renaissance spirit and Mannerism. Few villages in the Rhône corridor preserve sculpted decoration of this quality, and the contrast between the plainness of the outer walls and this profusion inside adds to the pleasure of discovery.

The Memory of Iron

In the 19th century, La Voulte was a key centre of French metallurgy. A company founded in 1823 by Lyon ironmasters built a battery of four coke-fired blast furnaces here, in operation from 1828. Activity peaked around 1870 before declining; the plant closed in 1889, the mines in 1892. The remains of the old foundries, protected as historic monuments, still stand near the river like a silent industrial cathedral, a rare testament to the early French iron and steel industry. Here, you realize how much the Rhône was an industrial artery before becoming a cruise backdrop.

Fossils, Birds and Riverbanks

La Voulte's subsoil is famous among palaeontologists the world over: its Jurassic fossil deposit, one of the most exceptional on the planet, has yielded marine organisms in a stunning state of preservation, including the oldest known octopus. Collections from the deposit can now be seen at the Muséum de l'Ardèche, located farther south in Balazuc; on site, it is the landscape that tells the story. The riverbanks, for their part, offer the Printegarde nature reserve, where herons and kites fly over the backwaters. Walkers and cyclists enjoy the paths that follow the water and head up the neighbouring Eyrieux valley, among orchards and hilltop villages.

Practical Pointers

• River boats moor in the immediate vicinity of the old town.
• The climb to the fortress follows steep, cobbled lanes; good shoes recommended.
• Princes' Chapel: access according to the town's opening hours or during guided tours.
• In summer, free concerts and festivals regularly liven up the town.
• Eyrieux valley and riverside cycle path for the more active.

You leave La Voulte with a lesson in mind: the most modest port calls sometimes hide the richest stories. Princes and blacksmiths, a fossil octopus and sculpted angels' heads share a few hectares of the Ardèche riverbank. When the boat resumes its course along the Rhône, the castle is the last to disappear, as if to check that you've taken note of everything.
