La Fondation Calvet is an art foundation in Avignon, named for Esprit Calvet, who left his collections and library to it in 1810. The foundation maintains several museums and a two libraries, with support from the town. The original legacies of paintings, archaeological items, coins and medals, and medieval sculpture have been added to by many other legacies, and a significant deposit of works of art from the Louvre. The archaeological collections and medieval sculpture are now housed separately in the 'Musée Lapidaire' - once the chapel of the Jesuit College. The main museum is in an 18th-century city mansion, to which modern buildings have been added; the Library bequeathed by Calvet, and the important collection of over 12,000 coins and medals, have moved to a different location in the city.
In Avignon there are six museums:
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.
