Located on the 5th floor of the Palais de Rumine, the department of zoology has exhibits from the 19th and even the 18th century. The permanent exhibition has an old-fashioned charm, especially the comparative anatomy room with its rows of jars, skeletons and two-headed monsters. 

In the galleries, some impressive pieces await visitors such as the tiger, the moose and the polar bear. The 5.89-metre great white shark is the largest stuffed specimen in the world. Temporary exhibitions are also regularly presented, as well as various events.
