A historic château founded around 1100 as a medieval priory is now on the market with Arrière-Cour Immobilier. Located in the village of Montanges in eastern France’s Jura foothills, the property sits on 3.6 hectares (8.9 acres) less than an hour from Geneva and is currently run as a bed-and-breakfast.

Château de Montanges presents an interesting opportunity to inhabit a site shaped by nearly a thousand years of history.

The property sits in the Jura foothills near the Swiss border, within reach of Geneva and the Pays de Gex, a region known for its cross-border lifestyle where many residents live in France while working in the Swiss city. Founded around 1100 as a Cistercian priory, the château reflects a long architectural evolution from monastic site to noble residence.

The Château de Montanges offers approximately 350 m² (3,767 ft²) of interior living space and retains a number of architectural elements from its medieval origins. Thick stone walls, vaulted spaces, monumental fireplaces, antique floors, and a spiral stone staircase remain visible throughout the residence. The layout includes roughly ten to twelve principal rooms depending on configuration, including reception salons overlooking the grounds and six to seven bedrooms with en-suite bathrooms.

Restoration work carried out over the past fifteen years introduced contemporary comforts while maintaining the historic character of the building. Period details such as carved doors, arched windows, and original arrow slits remain preserved throughout the château.

The estate extends across 3.6 hectares (8.9 acres) of landscaped grounds with views toward the Jura Mountains. Outdoor amenities include a swimming pool, spa area with Nordic bath, and an eight-person jacuzzi integrated into the surrounding landscape. The property also benefits from high-speed fiber-optic internet.

Additional structures expand the estate’s possibilities. Vaulted cellars, adjoining outbuildings, and usable attic areas provide roughly 300 m² of additional developable space, while a large barn arranged across three levels offers potential for further accommodation, reception spaces, or cultural uses.

An independent cottage certified by Gîtes de France—comprising a living room, two bedrooms, and a bathroom—forms part of the property’s existing hospitality operation. The château has been successfully operated as a bed-and-breakfast and guesthouse, with potential to expand the tourism activity through additional cottages or other structures subject to planning approvals.

Despite its secluded natural setting south of the Haut-Jura Regional Nature Park, the estate remains well connected. Bellegarde TGV station lies approximately fifteen minutes away, while the A40 motorway provides direct access to Geneva Airport in about forty-five minutes and Lyon Saint-Exupéry Airport in roughly an hour.

At the intersection of medieval heritage, alpine landscape, and proximity to one of Europe’s most international cities, the Château de Montanges presents an interesting opportunity to inhabit a site shaped by nearly a thousand years of history.
