Château de Balsac, Medieval castle in Druelle Balsac, France.

Château de Balsac is a castle in Druelle Balsac, Aveyron, built of rough light-beige and grey stone with reddish-brown accents. Its buildings stand around a courtyard; the main wing has Renaissance mullioned windows, circular towers and a keep, and the entrance door is framed by pilasters carrying a pediment. A wide round archway with a dark door opens at the base of a tall block, and a steep grey conical roof with a small spire rises behind.

The castle was burned in 1570 during fighting between Catholics and Huguenots, when Bertrand de Glandières was defeated and captured by the sire de Montaigut, who demanded a ransom of 2,000 gold écus paid by the Estates of Rouergue. Bertrand rebuilt the main dwelling with Renaissance mullioned windows. A siege is recounted in a chronicle of 1660. The building was listed as a Monument Historique in 2007.

The castle takes its name from the Balsac family, into which the poet Louis de Glandières (1561–1601) was born; he wrote under the name Louis de Balzac and dedicated a collection of French and Latin verse to Henri III. His tragedy Mustapha and a discourse addressed to the king at Blois in 1588 were printed. The seigneurie passed by marriage to the Faramond family in 1613.

The castle stands in the commune of Druelle Balsac, in the Aveyron department, at coordinates 44.40230, 2.44340. It is a private property, inscribed as a monument historique in 2007, and the buildings are arranged around a courtyard, so the entrance door framed by pilasters and a pediment is the point to look for when approaching.

The castle was bought in 1779 by Guillaume Grailhe for an annual life annuity of 4,800 livres, as recorded in the Balsac and Panat castle archives. His descendant Rose Grailhe inherited it and married Antoine Villa, a Rodez merchant turned judge, in 1786.
