Origin and history

Trohanet Castle, located mainly in the municipality of Briec (Finistère), also extends over Landudal and Langolen. Built in the 17th century on 15th century bases, it retains a medieval structure while integrating modernizations of the south and east facades around 1880. Its 25-hectare park, designed by the Bühler brothers in the late 19th century, includes a closed vegetable garden and a greenhouse, reflecting the evolution of landscape tastes of the era. The ensemble, inscribed in the historical monuments in 2001, illustrates the architectural and social transformations between the Ancient Regime and the contemporary era.

The family of Liziart, the first owner attested in the 15th century, transmitted the mansion by alliance to the Penancoet family of Keroualle in 1626. Louise de Keroualle, granddaughter of the owners, became Duchess of Aubigny thanks to her influence at the court of England and Louis XIV. In 1696, her mother, Marie de Ploeuc, sold Trohanet to the Treouret of Kerstrat, who rebuilt the present façade at the beginning of the eighteenth century. During the Revolution, the castle served as a refuge for the caulians, and Hyacinthe of Kerstrat was shot there in Brest in 1795 to 20 years.

The estate, which was acquired in 1851 by Admiral de La Grandière, governor of Cochinchina, was radically redesigned: the park was redesigned by Denis Bühler from 1872, and a new access driveway was created in 1903 by exchange of land with neighbouring municipalities. The property then passed through inheritance to the families of D'Espies and Pimodan, who undertook interior restorations until the 1980s. Today, the castle and its park, protected since 2001, bear witness to five centuries of Breton history, mixing aristocratic heritage and romantic landscapes.

The park, included in the additional inventory of historical monuments, includes 18th century outbuildings (grange, farm) and a 4 hectare pond. The Bühler brothers, renowned landscapers, applied their know-how by integrating natural elements and picturesque perspectives. The garden, surrounded by walls, and the 19th century greenhouse complete this whole, reflecting the self-sufficiency of the noble estates of the time.

Among the protected elements are the whole house, the facades of the communes, and the entire landscaped park. The castle, built of granite, dominates a piece of water and a hilly relief, typical of Breton landscapes. The interior decorations, redesigned in the 17th and 19th centuries, show the evolution of styles, from classicism to romanticism, while the family archives document the alliances and transmissions that shaped its history.

The last notable owner, Geneviève de Miillelle, widow of Lieutenant-Colonel François de Pimodan (died in Algeria), carried out extensive restoration work in the 1970s-1980s. His son, Baudoin de Pimodan, inherited the estate in 1988, continuing a lineage linked to Trohanet since the 17th century. The castle remains a remarkable example of architectural and landscape adaptation, where each time left its mark without clearing the traces of previous ones.
