Kosava castle is a ruined neo-Gothic castle built in 1830 by Graf Wandalin Puslowski. It is near the palace where Andrzej Tadeusz Bonawentura Kościuszko was born. The architect of the castle was Frantisek Yascholda. The ruined castle is similar to a replica of Tadeusz Kościuszko's house in Merechevschina. After the collapse of the January Uprising in 1863, ownership was transferred to the Trubetskoy family and other Russian aristocrats. During World War I and World War II, the place was severely damaged. Currently, the castle is in the process of restoration.
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.
