Museum de Fundatie owns and administers a substantial collection of art, accumulated by Dirk Hannema, the former director of the Boymans Museum. This collection was later supplemented with other major works, especially from the art collection of the Province of Overijssel.The collection and other, temporary exhibitions are on show at two splendid locations: Kasteel het Nijenhuis near Heino and the Paleis a/d Blijmarkt in Zwolle.
