The Natural History and Ethnographic Museum was founded around the collections of the Saint Louis brothers, which were used for visual education in the past.
The museum has several departments. The main attraction is the almost thousand stuffed animals on the first floor, which is still decorated in classical 19th century style. Many of the animals have been fitted into their natural surroundings in beautiful dioramas. Apart from a large collection of butterflies, there is also an archaeology department here, which grew out of the interests of Brother Christofoor, who in the 1950s collected archaeological finds in North Brabant and Limburg.
On the ground floor is a geology department with rocks, minerals and fossils. There is also an anthropology department with an exhibition on the White Fathers in Africa and an atmospheric room with African statues and masks.
The museum has had the predicate 'Registered Museum' since the end of 2004. This makes the Oudenboss Museum one of the official museums in the Netherlands.
