Origin and history

The Château Guillaume, located in the valley of the Allemette in Lignac (Indre), was built between 1087 and 1112 by Guillaume IX d'Aquitaine, nicknamed Duke Troubadour and singer of courteous love. This castle, symbol of the power of the Dukes of Aquitaine, then passed to his son Guillaume X, father of Alienor d'Aquitaine. The Romanesque dungeon, enlarged in the 13th century, was strengthened in the 14th century by four cylindrical towers and mâchicoulis, illustrating the evolution of medieval military techniques.

Dismantled under Richelieu, the castle was classified as Historic Monument in 1862 and restored in the 19th century by a disciple of Viollet-le-Duc, under the impulse of Countess Robert de Beauchamp. At that time, the village of Château-Guillaume, developed around the castle and its church, was attached to Lignac in 1819. The church, originally devoid of a bell tower, was rehabilitated in 1866-1868, while the dungeon received a roof in 1526 under the auspices of Claude Gouffier and his wife Jacqueline de La Tremeille.

The castle changed hands throughout the centuries, passing from the Dukes of Aquitaine to the Lords of La Tremeille (from the 12th to the 15th century), then to the Gouffier families, Riffaut, and La Faire. Among his notable owners, Georges de La Tremeille, Minister of Kings Charles VI and Charles VII, played a major political role. The site also preserves a Gothic bell of 1526, a witness to its religious and seigneurial history.

Architecturally, the castle combines medieval defensive elements (donjon, towers, mâchicoulis) and 16th and 19th century residential developments. Its enclosure, partially transformed into 19th century dwellings, reflects the adaptation of the monument to local needs. Today, it embodies both a military heritage, an aristocratic residence, and a historic village heart of Berry.
