Located just four kilometres from the Brittany coastline and overlooking the magnificent valley of the Aven River, this extraordinary estate embodies the timeless elegance and rich heritage of southern Brittany. Surrounded by unspoiled natural landscapes and offering breathtaking panoramic views, the property stands as a remarkable testimony to centuries of Breton history and architecture. Listed as a Historic Monument since 1935, this exceptional château combines a 15th-century structure, dating from around 1450, with a 19th-century extension, creating a harmonious blend of historical periods and architectural styles. Deeply connected to the legacy of Lord Jean de Cornouaille, an important historical figure of the region, the château has preserved all the authenticity and grandeur of a noble Breton residence while benefiting from a meticulous and comprehensive restoration. Between 2000 and 2007, the estate underwent an extensive renovation programme carried out with exceptional craftsmanship and strict respect for traditional building techniques. The restoration involved the renowned Compagnons du Devoir as well as the prestigious Perrault company, internationally recognised for its expertise and notably involved in the reconstruction of the timber framework of Notre-Dame de Paris. Thanks to this remarkable restoration, the château now perfectly combines historical authenticity with modern comfort and technical excellence. Offering approximately 1,200 square metres of living space, the château reveals impressive interiors filled with character, refinement and architectural beauty. The reception rooms are particularly spectacular, featuring monumental granite fireplaces crafted from the famous stone of Trégunc, elegant period details and generous proportions ideal for entertaining. Several refined lounges, reception rooms and libraries create a warm and prestigious atmosphere throughout the residence. The main kitchen, equipped by the prestigious French manufacturer La Cornue, combines timeless elegance with professional-quality equipment, perfectly suited for both family life and large-scale entertaining. Every space within the château has been thoughtfully designed to preserve its historic soul while meeting contemporary expectations of comfort and luxury. The property also offers a collection of elegant and individually themed suites, allowing guests and family members to enjoy exceptional comfort and privacy. The upper floors are organised around a spectacular spiral stone staircase, a true architectural masterpiece leading to the impressive guard room beneath a magnificent exposed timber roof structure rising to approximately fifteen metres in height. This extraordinary space perfectly illustrates the grandeur and authenticity of the château. The estate extends across approximately 37 hectares of preserved land, composed of meadows, woodland and open natural areas. The surrounding landscape offers absolute tranquillity and uninterrupted views over the Aven valley, creating a unique atmosphere of serenity and exclusivity. Numerous outbuildings further enhance the remarkable character of the estate. These include a beautifully reconstructed 16th-century chapel, a fully renovated caretaker’s house, stables, a traditional flax drying house and a farmhouse of approximately 200 square metres awaiting renovation according to future projects or personal inspiration. The property also features magnificent restored market halls built in oak and covered with traditional Sizun slate, a 300-square-metre storage building and a superb natural swimming pool with ecological filtration, perfectly integrated into the surrounding landscape. Beyond its historical significance and architectural prestige, the château benefits from high-quality modern technical installations designed for year-round comfort and energy efficiency. The estate is equipped with an advanced geothermal heating system supported by twelve boreholes, ensuring excellent environmental performance while preserving the integrity of the historic structure. Rarely does a property of such historical importance, architectural beauty and natural setting become available on the market. Combining heritage, elegance, privacy and modern comfort in one of Brittany’s most beautiful environments, this exceptional château offers a truly unique lifestyle opportunity in the heart of southern Brittany.
