St. Hans and St. Peter churches were built side by side during the 1200s. St. Peter was consecrated to the apostle Peter. St. Hans, which was the larger church, was dedicated to St. John the Evangelist. It was where the Lutheran doctrine for the first time preached on the island. In 1527, however, Bishop Brask turned Lutherans out from the church. But as soon as the bishop sailed to Denmark, Lutherans worships were started again. Churches were demolished in 1600-1800s and the stone was used among others to construct Lythbergska house. In 1982 a beautifully decorated gravestone was found in the ruins of in St. Hans, dating from 1050s.
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.
