History+
The castle's origins date back to the 13th century. The estate belonged to families such as the Courtenays, Aubusson-La Feuillade, and d'Aguesseau. Through Henriette d'Aguesseau, it came into the possession of her daughter Adrienne de La Fayette, who passed it on to her husband, General Gilbert du Motier, Marquis de La Fayette. He resided at the Château from 1802 until his death in 1834. After La Fayette's passing, his grandson Jules de Lasteyrie and his wife Olivia de Rohan-Chabot lived on the estate for 54 years. In 1935, their son Louis de Lasteyrie sold the property to his cousin René de Chambrun, who, after the previous owner's death in 1955, discovered documents in the attic. This led to the establishment of a private museum in honor of La Fayette and the safeguarding of the family archives, which include documents dating from 1457 to 1990.
