Saarburg Castle was one of the first and most impressive castles (Höhenburgen) in the West, built by Graf Siegfried von Luxemburg in 964. It was damaged in 1431 by troops of Ulrich von Manderscheid. Johann II von Baden rebuilt the castle later. It was conquered several times in the wars of 17th-early 18th century and finally left to decay in 1734.

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.
