Montemayor del Río Castle probably doesn't date back to before the 15th century, and has more the character of a palace than of a strength. It has two existing enclosures. From the outer one only the entrance, flanked by two turrets, remains. The inner has an irregular groundplan, adapted to the outline of the land it was build on.
In the interior two floor levels can still be traced which were arranged around a central patio. In the left wall a large chimney is conserved, evidence of habitation.
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.
