The Abbey Church of Notre-Dame, sometimes referred to as 'Montivilliers Abbey' dates back to 684, although it was destroyed a Viking raid in 850, and rebuilt as a church in both the Romanesque and Gothic styles. It fell into decline by the late 1700's. Its decline went up to the French revolution at the end of the 18th century when it was closed and sold. Fortunately the abbey was not destroyed and was later bought back by the city of Montivilliers. An ambitious restoration program which was completed in 2000 gave back to the abbey its splendor.
Besides the church, it now houses exhibition rooms and the cloister has regained its elegance. The plan of the abbey is a traditional one: western building mass with two towers, large un-vaulted nave, projecting transept, lantern tower and gradated tower. The older parts are located in the choir and in the base of the western mass which dates from the end of the 11th century.From the renovated refectory to the rebuilt cloisters, and from the chapter house to the dormitory, as part of a moving museum exhibit that vibrantly evokes the nuns' lives, the abbey's history and its architecture.
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.
