The Musée d'Orsay was built between 1898 and 1900. The museum holds mainly French art dating from 1848 to 1915, including paintings, sculptures, furniture, and photography. It houses the largest collection of impressionist and post-impressionist masterpieces in the world, by painters including Monet, Manet, Degas, Renoir, Cézanne, Seurat, Sisley, Gauguin and Van Gogh. Many of these works were held at the Galerie nationale du Jeu de Paume prior to the museum's opening in 1986.
The museum building was originally a railway station, Gare d'Orsay, constructed for the Chemin de Fer de Paris à Orléans and finished in time for the 1900 Exposition Universelle to the design of three architects: Lucien Magne, Émile Bénard and Victor Laloux. It was the terminus for the railways of southwestern France until 1939.
By 1939 the station's short platforms had become unsuitable for the longer trains that had come to be used for mainline services. After 1939 it was used for suburban services and part of it became a mailing centre during World War II. It was then used as a set for several films, such as Kafka's The Trial adapted by Orson Welles, and as a haven for the Renaud–Barrault Theatre Company and for auctioneers, while the Hôtel Drouot was being rebuilt.
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.
