The Gustavianum, named after its patron, Gustave II Adolf, stands on the site of a medieval episcopal palace and housed the university from 1620 to 1887. The cupola with a sun on top allowed light into the anatomy amphitheatre (1663), where naturalist and professor of medecin, Olof Rudbeck (1630-1702) carried out his public dissections. A museum retraces the history of the university and has a section dedicated to prehistoric and medieval Sweden. The superb Augsbourg cabinet of curiosities was given to King Gustave II Adolf in 1632 by this German town.
