Château de Trégranteur, Historical castle in Guégon, France
The central building of Château de Trégranteur features two wings with projecting pavilions, following the architectural style of Louis XIV period.
Built in 1750 by architect Hippolyte de Brilhac for René-Jean Bonin, a parliament councilor of Brittany who acquired the estate through marriage.
The ground floor rooms contain Louis XV wood panels, while the library and salon doorways display pastoral scenes painted in monochrome.
The exterior areas of the castle remain accessible to visitors, while the interior sections maintain private status under departmental ownership.
The entrance gate, crafted by Eustache Roussin in 1750, displays intricate ironwork featuring the combined family crests of Bonin and Saint-Pern.
