The east wing of Gram Castle was built in the beginning of the 16th century. The builder is unknown, but was probably one of the Reventlow family, who owned Gram from about the middle of the 15th century until 1560. The south wing was built by the Commander Hans Schack (1609 - 1676) a few years after he bought the manor in 1664. The west wing of the manor was built 1752 by Countess Anna Sophie Schack (1689 - 1760). Today it is a conference center.
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.
