THE SALE OF THE ESTATE IN THE 19th CENTURY
In 1809, all of the property was sold at auction following the death of the last Marquise de Thézan, who had died without descendants.
Her niece, Olympe de la Baume-Suze, acquired the estate. She sold it in 1814 to Louis, Marquis Pelletier de Gigondas de La Garde.
The Marquis, accustomed to a sumptuous lifestyle, undertook extensive decoration and comfort work to restore the castle to its former glory. These receptions will make the reputation of Thézan beyond the regional borders.
His son Henri succeeds him and continues the embellishments. He was responsible for transforming the southern façade into a fashionable neo-medieval style, giving it a romantic charm. It was at this time that the french garden was given the appearance of an english park. Ruined by the Castle and an expensive lifestyle, he was forced to sell the castle in 1862.
