The Château de Montignac is a ruined castle in the commune of Montignac-Charente, in the Charente département of France.
The castle is located at the crossroads of two important roads, the Via Agrippa from Saintes to Lyon where it crosses the Charente, and Via Chaussada from Périgueux to Poitiers.
Guillaume II, Count of Angouleme obtained from the bishop of Angoulême, the fief and right to build a castle, with the stones of the Andone Castrum.
[2] In the 12th century, ownership of the castle was disputed between Gerard de Blaye, helped by the lords of Saintonge and Poitou, and Vulgrain II of Angouleme, supported by the Duke of Aquitaine.
In 1350, it was in the hands of Pierre II d'Amboise, viscount of Thouars, before being bought by La Rochefoucauld family on 13 January 1399.
