Origin and history

Kerduel Manor House, located in the eponymous hamlet of the commune of Lignol (Morbihan, Brittany), is a composite building built in three countrysides. The first house, erected in the 16th century, consists of two wings articulated around a stone screw staircase, while a western pavilion with a high four-sided roof, dating from the 17th century, is attached to it. At the back, a later appentis completes the whole, which also includes a cylindrical tower with a remarkable staircase. The facades and roofs of the mansion were listed as historical monuments in 1989, after its acquisition in 1989 by François Adda, who began its restoration.

The seigneury of Kerduel, attested from 1437, originally belonged to Jean Le Courhin, vassal of Charles de Rohan, sire of Guémené. Transmitted by successive alliances — notably to Louis d'Outreville in 1589, then to the families of Pérenno and Le Vicomte — the mansion changed hands several times before being transformed into a farm by the Guyomard family. Its history reflects the seigneurial and matrimonial dynamics of the Ancien Régime Brittany, marked by hereditary transmissions and strategic marriages. The inscriptions on the well (1838) and the shed (1799) bear witness to continued occupation until the modern era.

Architecturally, the mansion combines defensive and residential elements characteristic of the sixteenth and seventeenth centuries. The facade, adorned with sill windows, contrasts with the cylindrical staircase tower, typical of Breton noble houses. The 17th century pavilion, with its cornice on modillons, illustrates the evolution of tastes towards more comfort and ornamentation. Ranked for its facades and roofs, the building today embodies both historical and architectural heritage, preserved despite the risks of demolition mentioned in the 20th century.
