Cismar Abbey was a Benedictine monastery founded in 1238 by Count Adolf IV of Holstein as alternative accommodation for Benedictine monks from Lübeck. In the mid-15th century it was one of the six original members of the influential Bursfelde Congregation, a Benedictine reform movement. After three prosperous centuries, based largely on its possession of a relic of the blood of Christ and a healing spring dedicated to John the Baptist, which made it a centre of pilgrimage, it was dissolved in 1561 during the secularisation brought about by the Reformation. The monastic library is preserved in the Danish Royal Library in Copenhagen.
The abbey is famous for its carved altar, dating from early in the 14th century, still in place in the church. The other surviving buildings, after a wide variety of secular uses, now serve as a museum.
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.
