Aulne Abbey was a Cistercian monastery, founded by Saint Landelinus about 637. Before 974 the Benedictines were replaced by secular clerics leading a common life, who, however, embraced the Rule of St. Augustine in 1144.
At the instance of Henry de Leyen, Bishop of Liège, it came into the hands of Cistercian monks from Clairvaux in 1147, under Franco de Morvaux as its first Cistercian abbot. From that time onwards it flourished as a Cistercian monastery.
The French burned it at the end of the 18th century, only a short time after it had been rebuilt on a larger scale. The library, which contained 40,000 books and 5,000 manuscripts, was also destroyed.

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.
