Château de Montpensier Wikipedia
From the 11th century, Château de Montpensier was known as the fortress of Mons Pancherii (literally, Mont de la Panse, by reason of the shape of its motte). On 8 November 1226, King Louis VIII died there following a violent fever during his return from the Albigensian Crusade.
During the Hundred Years' War, the castle was still a strategic site that necessitated it being taken tower by tower by the English. Cardinal Richelieu ordered the destruction of the castle in 1633.
