Nanstein Castle was built around the year 1162 after Holy Roman Emperor Frederick I demanded its construction as additional defense for the Palatinate.
In 1504, German knight Franz von Sickingen, inherited part of the castle after his father's death in the War of the Bavarian Succession, finally acquiring the entire castle in 1518. He immediately began extensive refortification to make the castle suitable for firearms.
Nanstein is well known for an elaborate siege during the Knights' Revolt in 1523 which claimed the life of von Sickingen. The fall of Nanstein was a symbol for the decline of castles in the Palatinate.
In 1542, von Sickingen's sons recovered Nanstein as a fief and started reconstruction of the castle. Reinhard von Sickingen completed the reconstruction in 1595. In 1668, Elector Charles I Louis forced Lotharingian troops from the castle and razed the fortifications.
In the 19th century the first conservation work was done on Nanstein, and this has continued to the present day.
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.
