Château de Trégranteur

Château de Trégranteur is a castle in Guégon featuring a central building with two wings and projecting pavilions following the Louis XIV architectural style. The layout displays typical proportions and symmetrical elements characteristic of its period.

The castle was constructed in 1750 by architect Hippolyte de Brilhac for René-Jean Bonin, a parliament councilor of Brittany who acquired the property through marriage. This family union influenced the design and development of the estate.

The ground floor rooms contain wood paneling from the Louis XV period, while doorways in the library and salon display pastoral scenes rendered in monochrome tones.

The exterior areas of the castle remain accessible to visitors, while the interior sections retain their private status under departmental ownership. Plan to explore the outdoor spaces and architectural details from different vantage points.

The entrance gate was crafted by Eustache Roussin in 1750 and displays intricate ironwork featuring the combined family crests of Bonin and Saint-Pern. This detailed work reflects the union of two important families.
