Eleven centuries above the Isère
Why this place matters
Set on a rocky outcrop above the Isère, Château de la Sône brings together several layers of history: a medieval stronghold, a residence reshaped in the early 17th century, parkland reworked in the late 19th century, and today a place of hospitality and events. Its silhouette speaks of the Dauphiné, the region's silk memory, and the enduring art of living in a grand estate.
A fortified stop on the river, a robe-nobility residence, a place tied to the silk trade, and later a country estate: Château de la Sône holds several chapters of local history within one site.
Local tradition places an Allobroges oppidum on this promontory, suggesting a very early human presence on this natural lookout above the river.
What is more firmly established is the existence of a fortified house mentioned in 1210 in letters patent attributed to Holy Roman Emperor Otto IV. By then, the site already appears as a strategic position on the Isère corridor.
In the first half of the 14th century, the building was enlarged and its defenses strengthened in the orbit of Dauphin Humbert. A century later, in 1448, the dauphin Louis, the future Louis XI, stayed here, confirming the importance of the site within the Dauphiné.
The Wars of Religion dealt the château a severe blow. Between 1562 and 1598, Catholics and Protestants fought over it; Lesdiguières laid siege to the place, and the complex emerged deeply damaged from that troubled period.
In 1603, Horace du Rivail sold the lordship of La Sône to Félicien de Boffin, Attorney General at the Parliament of Grenoble. With him, robe nobility replaced military nobility.
Félicien de Boffin repaired the damage left by the Wars of Religion and gave the château much of its classical profile. The Boffin family remained in place for nearly two centuries, and the estate was raised to a marquisate around 1732.
During the Revolution, the château narrowly escaped dismantling under the order of 15 Thermidor, Year I. In 1820 it passed to the Jubié family, whose name was closely tied to La Sône's silk history through the Royal Manufactories established in the 18th century.
The site also remains closely linked in local memory to Jacques de Vaucanson and to silk-winding innovation. In the 19th century, Stendhal still referred to the château, the Jubié family, and the silk machinery in his pages on the Dauphiné.
The transfer to the Jubié family was cancelled in 1848, after which several owners followed. The Mérimée record dates a major restoration campaign and the redesign of the park to around 1890. The façades, roofs, and chapel have been listed since November 6, 1968; the park since June 30, 1995, with an updated protection order in 2016.

Beyond stonework and dates, the château also survives through the memories, stories, and impressions of those who passed through it.
In Memoirs of a Tourist, Stendhal evokes the 'curious château of La Sône,' a bridgehead above the Isère, and recalls the Jubié family, the silk works, and Vaucanson's machines.
In the 20th century, local memory links the château with Françoise Sagan's stays with the Morel family. That association is often, cautiously, connected with the imaginative world of Château en Suède.
The second half of the 20th century leaves the image of a lived-in house, welcoming visitors from the arts, letters, science, and industry within a park once again used for strolling and conversation.
