The Museum of Natural History and Ethnology has several departments with various collections.
The 'main attraction' are almost a thousand mounted animals on the first floor. Many animals are shown in their natural environment. There is an extensive collection of butterflies as well.
The archaeological department sprung from the interests of brother Christofoor, who collected archaeological finds from the Southern parts of the Netherlands as early as the fifties of the last century.
Then there is a geological department with stones, minerals and fossils; there is a room with African art objects and utensils brought back by missionaries (White Fathers) during the 19th and 20th century; and there is an environmental department, which offers all manner of things to see and to do on subjects such as wind and nuclear energy, climate change, glacials, soil pollution and waste processing, as well as a weather station.
The museum holds an official registration since 2004. This is a distinctive for Dutch museums that conform to high standards of professionalism. The museum is proud to be reckoned among these.
