Biburg Abbey was a house of the Benedictines founded in 1132 by Konrad and Arbo von Sittling-Biburg. They were sons of the Blessed Berta of Biburg, who donated their castle to the Bishop of Bamberg for the purpose. The foundation was originally a double monastery for both men and women; the nunnery however burnt down in 1258 and was not re-built.
In 1555 the monastery was dissolved and the premises came into lay hands. In 1589 the Jesuit College of Ingolstadt obtained the buildings, which were taken over in 1781 by the Knights Hospitaller. In 1808 the monastery was secularised and passed into the possession of the Bavarian State.
The abbey church has remained mainly unchanged from its inauguration in 1140.
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.
