Östergarn church is a little 13th century church where the tower of was never built. It was burnt by the Swedes in 1565 during the Nordic Seven Years' War, whereat all medieval fittings were destroyed. It was also sacked by the Russians in 1715 and 1717. In a grave in the church yard lie the German seamen who fell on board the cruiser Albatross, when she was compelled by superior Russian forces to run ashore near the fishing village of Herrvik in Östergarn in 1915.
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.
