The largest Swiss museum in its field opened in a modern building in the 1960s.
In the collections are insect specimens collected by the 18th and 19th century entomologist Louis Jurine.
But what catches most people’s attention is the army of taxidermies on the ground floor.
The museum also has living animals, and you have to meet Janus, the spur-thighed tortoise with two heads which was born in incubators at the museum in 1997.
