History+
Between the 11th and 14th centuries, the lords of Anduze, Randon, and Polignac paid homage to the abbot of Saint-Pierre-de-Sauve for this castle. In 1322, Raymond Guillaume de Budos, a nephew of Pope Clement V, acquired the seigniory. He expanded the complex in 1384 with at least two additional flanks. Thibaud de Budos recovered the castle after deposing his father André, who had joined the English at the beginning of the Hundred Years' War. The seigniory grew rich and powerful until Louis XII elevated it to a marquisate in favor of Antoine Hercules de Budos, to whom the castle's present form is attributed.
