The Château de la Bourdaisière is a 19th-century county house in the Commune of Montlouis-sur-Loire, in the Indre-et-Loire département of France.
The site of the present house dates back to the 14th century when it was a fortress belonging to Jean Meingre. Over the next few generations, the property changed hands several time, until 1520 when King Francis I arranged for construction of a new castle on the site. Built for his mistress, , the wife of Philibert Babou, Superintendent of Finances for France, after her death, the property would remain in the family's hands.
Marie Gaudin's granddaughter, Gabrielle d'Estrées, was born in the château and would herself grow up to become mistress to another king, Henry IV of France.
In 1775, the château was partially destroyed by order of King Louis XV's most powerful Minister, Étienne François, Duc de Choiseul. Étienne François wanted to use the stones from Château de la Bourdaisière for the construction of his Pagoda at his estate in Chanteloup, near Amboise.
Lying in ruins, in 1786 the land was sold to Louise Adélaïde of Penthièvre Bourbon. In 1802 the property was acquired by Baron Joseph Angelier who undertook a massive reconstruction of Château Bourdaisière. The interior work would be completed by his son, Gustave Angelier. Although a small château, when compared to the great châteaux of the Kings and some of those built by other wealthy nobles, it is a magnificent Renaissance construction fronted by traditional French gardens.
The Castle was sold in 1923 to a wealthy American, Mrs. de Mérinville who sold it in 1938. During World War II, the château was occupied by the Nazis. After the war, a lack of funds by its owner saw it become severely run down. In 1959, its contents were auctioned off and government turned the château into a home for the elderly.
