The Burg Liebau is the ruin of a spur castle on a flat rock spur on the right flank of the Elster. The castle was first mentioned in a document in 1327. In the 14th century exchanged Plauen Vogt Heinrich the Elder including the castle with the Wettiners and 1441 the castle was owned by the Dölau, of which the castle from 1500 to 1550 graduated like in Renaissance style was rebuilt.
In 1640 the castle was sacked by Swedish mercenaries and the stair tower was set on fire. The castle remained with its last owner Gottlob Christian von Doelau on Ruppertsgruen and his wife Sophia Christina geb. von der Planitz owned it until 1725, was then owned by Johanna Charlotte von Beust until 1742 and then fell into disrepair.
From 1995 to 1997 security work took place in cooperation with the State Office for Archeology and is now a ground monument .
The castle complex on an approximately triangular plateau measuring 50 by 30 meters probably consisted of a defensive and residential tower , the gate tower and a surrounding wall with battlements , further protected by two section trenches that were approx. 5 meters wide and 2 meters deep. The actual castle ruin has the dimensions of 20 to 25 meters. To the east, the complex was protected by a partially natural 20 to 25 meters wide and 5 to 6 meters deep neck ditch with a drawbridge.
References: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.
