Origin and history

The Baronnais mansion, built in the 2nd quarter of the 17th century (1647), embodies the Breton Renaissance style with its imposing roofs, monumental fireplaces and wrought iron grilles adorned with crosses and lily flowers. Inside, the ground floor houses a large entrance, a stone kitchen in Saint-Cast, and a living-dining room with woodwork and marble fireplaces of the era. The granite staircase serves two floors with preserved rooms, while a French garden structured in terraces, deep wells and box alleys completes the whole.

The mansion is inseparable from the history of the Ladvocat family of the Baronnais, then the Colas de la Barre who inherited it in 1757. During the Revolution, he became a refuge for the persecuted, with an underground network leading to the beach via legendary tunnels. The family, decimated by the events, sees one of its daughters, Renée-Rose, escaping from the drownings of Nantes and marrying in secret in the dining room. The estate then passed to the Gouyon Matignon and Sonis until 1925, before being acquired by private owners such as Mrs.Sassoon or the Drouin (since 1955).

Ranked a historic monument in 1972, the mansion protects its facades, roofs, and interior decorations (living room, dining room, bedroom). Its history combines feudality (rights of justice and Dinard-Saint-Malo passage), Resistance (network of escape to Jersey), and architectural heritage, with elements such as the two deep wells or the terrace decorated with blue cedars. Today, there remains an intact testimony of Breton seigneurial life from the 17th to the 20th century.
