Château de Castelnoubel is situated on a promontory overlooking the Mondot valley near Bon-Encontre. The site where the castle stands has been occupied since the 10th or 11th century. Construction of the current castle began in the late 13th century. It belonged to the Marmande family initially, with Arnaud de Marmande being the first known lord. The Durfort family took ownership after the Marmandes, with Arnaud de Durfort receiving jurisdiction rights from Charles le Mauvais, King of Navarre. The Durforts continued to hold Castelnoubel until the late 16th century, when it passed through marriage to the Secondat family.
In the early 18th century, Castelnoubel came into the possession of Louis Pascault de Poléon and remained in the Pascault de Poléon family until the 19th century.Pierre Loubat and later Joseph-Marie-Étienne Giraud, who served as secretary general of the prefecture of Agen, were subsequent owners.The castle eventually became a historic monument in 1966.
Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
