The Bibliotheca Thysiana was erected in 1655 to house the book collection of the lawyer Johannes Thysius (1621–1653). Upon his early death, he left a legacy of 20,000 guilders for the building of a public library with a custodian's dwelling. Designed by the architect Arent van ‘s-Gravensande, the building follows the Dutch Classical style and is regarded as one of the jewels of Dutch 17th-century architecture.
The Bibliotheca Thysiana is the only surviving 17th century example in the Netherlands of a building that was designed as a public library. It is quite extraordinary that a complete private 17th century library has been preserved and thus offers a good impression of the book collection of a young, learned bibliophile from the period of late Humanism. The collection contains about 2,500 books and thousands of pamphlets in all scientific fields.
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.
