Origin and history

Château des Onglées is an iconic building located in Acigné, Ille-et-Vilaine, Brittany. Built in the early seventeenth century, it embodies the architecture of the pleasure houses erected by the Breton parliamentarians around Rennes. The estate is organized around four main buildings: a hunting lodge dating from 1595-1605, a house of the years 1630-1640 renovated in the 18th and 19th centuries, a chapel completed in 1677, and a farm with an old farmhouse of 1670. The chapel houses wooden paintings illustrating psalms of the Song of Songs, adding an artistic and religious dimension to the site.

The castle was originally acquired in 1632 by Hervé de Coniac, an adviser to the parliament of Brittany, who launched its construction. His son, Jean de Coniac, continued the work. In the 19th century, Alain Léon de Tréverret and his wife Noemi de Coniac, owners of the premises after their marriage in 1818, renovated the castle and built an English park. Their grandson, Alain de Treverret, became mayor of Acigné from 1902 to 1929, marking the local anchor of the family. The estate, registered with historical monuments since 2012, illustrates the architectural and social evolution of the Breton nobility over four centuries.

The Château des Unglées is distinguished by its spatial organization, with buildings aligned north-south, including an isolated pavilion to the north (old stables according to an oral tradition) and a chapel buried under the groves to the east. The roofs, with long sections or pavilions, reflect the styles of the 17th and 18th centuries. The landscaped park, structured by ditches, a basin and aisles, as well as the proximity to Vilaine, make it a remarkable example of the houses of the aristocratic fields near Rennes, the seat of the Parliament of Brittany before the Revolution.

The arms of the Léon de Tréverret family, visible on the west facade, testify to their possession of the estate since the Restoration. The castle, with its protected elements (logis, chapel, park), offers a complete panorama of local history, mixing architectural heritage, parliamentary life and landscape transformations. Its inscription in 2012 devotes its historical and aesthetic value, while emphasizing its role in the history of Acigné and Brittany.
