Le château en bref
According to tradition, the Château d'Olbreuse, in Usseau (Deux-Sèvres), was built in the 11th century, although archival records are lacking to date its construction precisely; its original medieval layout formed a fortified rectangle with towers at the corners. The château owes its renown to Éléonore Desmier d'Olbreuse, born around 1639, probably on the estate, daughter of Alexandre Desmier d'Olbreuse (1608–1660): married to the German prince George William of Brunswick-Lüneburg, she became the mother of Sophia Dorothea, wife of King George I of Great Britain, which earned her the nickname “grandmother of Europe”. A place of Protestant refuge, the château is said by local tradition to have been set on fire 27 times; in 1685, Protestants were hidden in its underground passages, and Louis XIV placed it under sequestration in 1702 to punish Éléonore, before lifting the measure in 1707. The building was restructured around 1760 by the Prevot de Gagemont family, with the windows enlarged in the 18th century and the upper floor raised at the end of the 19th century; an original vaulted cellar survives beneath the central main building. During the First World War, the château served as a hospital for blinded wounded soldiers, then operated as an inn offering seminars and dining from 1983 to 1996. Since 1996 it has belonged to the Boscals de Reals family.
