Dragsmark Abbey was a Premonstratensian canonry, also known as Marieskog in Norwegian. It was founded before 1260, with the support of King Håkon Håkonsson, and was dedicated to the Blessed Virgin Mary. The abbey was very wealthy in its heyday and ran a prestigious school, but declined during the 15th century, and as early as 1519 was in the control of a lay administrator, the first monastery in Norway to be secularised. With the Reformation the Crown granted it to a tenant in 1532, with a condition that the remaining canons had to be maintained. The buildings fell into disrepair, and in 1610 were used as a quarry for stone for the construction of Båhus Fortress.
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.
